a) Range:

Well, if the golf ball is anything like my golf game, the range is probably going to be quite impressive. But let's crunch some numbers to find out for sure! With an initial velocity of 35 m/s and an angle of 35 degrees above the horizontal, we can break down the initial velocity into its horizontal and vertical components.

The horizontal component is given by v₀x = v₀ * cos(theta), where v₀ is the initial velocity and theta is the angle. So, v₀x = 35 * cos(35) = approximately 28.71 m/s.

Now, to find the time of flight (t), we can use the equation t = (2 * v₀ * sin(theta)) / g, where g is the acceleration due to gravity (approximately 9.8 m/s²). Plugging in the values, we get t = (2 * 35 * sin(35)) / 9.8 = approximately 4.58 seconds.

Finally, we can find the range using the equation R = v₀x * t. Substituting the values we obtained, R = 28.71 * 4.58 = approximately 131.63 meters.

b) Maximum Height Reached:
To calculate the maximum height, we can use the equation h = (v₀y²) / (2 * g), where v₀y is the vertical component of the initial velocity. Using the formula v₀y = v₀ * sin(theta), we find v₀y = 35 * sin(35) = approximately 19.73 m/s. Plugging that into the equation, we get h = (19.73²) / (2 * 9.8) = approximately 19.2 meters.

c) Time of Flight:
We already calculated the time of flight in part a), which is approximately 4.58 seconds.

So there you have it! The range is approximately 131.63 meters, the maximum height reached is approximately 19.2 meters, and the time of flight is approximately 4.58 seconds. And remember, no matter how far that golf ball flies, it's always a struggle to find it in the rough! Good luck!

To solve this problem, we can use the kinematic equations of motion to find the range, maximum height, and time of flight of the golf ball. Let's break it down step by step:

Step 1: Decompose the initial velocity into its horizontal and vertical components.
The horizontal component of the initial velocity can be calculated using the equation Vx = V * cos(theta).
The vertical component of the initial velocity can be calculated using the equation Vy = V * sin(theta).
Using the given values, we can calculate:
Vx = 35 m/s * cos(35°)
Vy = 35 m/s * sin(35°)

Step 2: Find the time of flight.
The time of flight is the total time it takes for the ball to reach the ground. We can calculate it using the equation T = 2 * Vy / g, where g is the acceleration due to gravity (approximately 9.8 m/s^2).
T = 2 * Vy / g
Note: In this equation, we multiply Vy by 2 because the time of ascent (going up) is equal to the time of descent (coming down).
T = 2 * (35 m/s * sin(35°)) / 9.8 m/s^2

Step 3: Find the range of the golf ball.
The range is the horizontal distance traveled by the golf ball during the time of flight. We can calculate it using the equation R = Vx * T.
R = Vx * T
R = (35 m/s * cos(35°)) * T

Step 4: Find the maximum height reached by the golf ball.
The maximum height is the vertical distance from the ground to the highest point reached by the golf ball. We can calculate it using the equation H = (Vy^2) / (2 * g).
H = (Vy^2) / (2 * g)
H = (35 m/s * sin(35°))^2 / (2 * 9.8 m/s^2)

Now, substitute the values and calculate the answers:

a) Range:
R = (35 m/s * cos(35°)) * T

b) Maximum height:
H = (35 m/s * sin(35°))^2 / (2 * 9.8 m/s^2)

c) Time of flight:
T = 2 * (35 m/s * sin(35°)) / 9.8 m/s^2

To find the answers to these questions, we can break down the given information into two components: the horizontal and vertical motions of the golf ball. Let's start by analyzing the horizontal component.

Horizontal motion:
1. The initial velocity (u) of the golf ball in the horizontal direction is given as 35 m/s.
2. The angle (θ) above the horizontal is given as 35 degrees.
3. The horizontal component of the initial velocity (u_x) can be calculated using trigonometry: u_x = u * cos(θ).

Vertical motion:
1. The initial velocity (u) of the golf ball in the vertical direction is also given as 35 m/s.
2. The angle (θ) above the horizontal is given as 35 degrees.
3. The vertical component of the initial velocity (u_y) can be calculated using trigonometry: u_y = u * sin(θ).
4. The acceleration (a) in the vertical direction is due to gravity and is approximately -9.8 m/s² (assuming no air resistance).

Now, let's answer the given questions:

a) Range:
The range is the horizontal distance covered by the golf ball. It can be calculated using the formula: Range = Horizontal component of initial velocity (u_x) * Time of flight (t).

To find the time of flight, we can use the equation: t = (2 * u_y) / a.

1. Calculate the horizontal component of the initial velocity (u_x):
u_x = u * cos(θ) = 35 m/s * cos(35°).

2. Calculate the time of flight (t):
t = (2 * u_y) / a = (2 * u * sin(θ)) / a = (2 * 35 m/s * sin(35°)) / (-9.8 m/s²).

3. Substitute the values back into the Range formula to find the value of the range.

b) Maximum height reached:
The maximum height is the highest point that the golf ball reaches in its vertical motion.

1. Calculate the time it takes for the golf ball to reach its maximum height:
To find the time (t_max) taken to reach the maximum height, we can use the equation: u_y = u * sin(θ) = u_max * sin(90°), where u_max is the maximum velocity attained in the vertical direction.
Since the total time of flight (t) is equal to twice the time taken to reach the maximum height (t_max), we can substitute t = 2 * t_max and solve for t_max.

2. Calculate the maximum height (h_max):
We can use the formula: h_max = u_y² / (2 * |a|), where |a| is the absolute value of the acceleration due to gravity.

c) Time of flight:
The total time of flight is the time taken for the golf ball to return to the ground.

We have already calculated the time of flight (t) in step 2 when finding the range.
