To calculate the range of the sphere, we need to consider the horizontal motion of the sphere after it leaves the ramp.
The horizontal motion of the sphere is not affected by the downward tilt of the ramp. Therefore, we can assume that the horizontal velocity of the sphere remains constant at 1.5 m/s.
To calculate the range, we need to find the horizontal distance the sphere travels before it hits the floor. This can be done by multiplying the horizontal velocity by the time of flight.
To find the time of flight, we need to determine the vertical distance the sphere falls from the bottom of the ramp to the floor. We can use the equation for free-fall motion to calculate the time it takes for the sphere to fall this distance.
Let's calculate the time of flight first.
Using the equation for free-fall motion:
h = (1/2) * g * t^2
Where:
h = vertical distance
g = acceleration due to gravity (approximately 9.8 m/s^2)
t = time of flight
Plugging in the values:
0.90 m = (1/2) * 9.8 m/s^2 * t^2
Solving for t:
t^2 = (2 * 0.90 m) / 9.8 m/s^2
t^2 = 0.1837 s^2
t ≈ 0.428 s
Now that we have the time of flight, we can calculate the range.
Range = horizontal velocity * time of flight
Range = 1.5 m/s * 0.428 s
Range ≈ 0.642 m
Therefore, the range of the sphere is approximately 0.642 meters.
To calculate the range of the sphere, we need to consider the motion of the sphere in the horizontal direction.
The range is the horizontal distance traveled by the sphere before it hits the floor.
To calculate the range, we can use the equation:
Range = Initial Velocity x Time of Flight
To find the time of flight, we need to determine how long the sphere is in the air.
To calculate the time of flight, we can use the equation:
Time of Flight = (2 x Initial Velocity x sin(angle)) / g
where:
- Initial Velocity is the velocity at which the sphere leaves the ramp (1.5 m/s in this case).
- angle is the angle at which the ramp is tilted downwards.
- g is the acceleration due to gravity (approximately 9.8 m/s²).
Given that the bottom of the ramp is 0.90 m above the floor, we can use this information to determine the angle at which the ramp is tilted downwards.
To calculate the angle, we can use the equation:
angle = tan⁻¹(vertical distance / horizontal distance)
where:
- vertical distance is the height difference between the bottom of the ramp and the top of the ramp.
- horizontal distance is the length of the ramp.
In this case, the vertical distance is 0.90 m and the horizontal distance can be determined based on the geometry of the ramp.
Once you have the angle, you can substitute the values into the equation for the time of flight and then use that value to calculate the range using the equation mentioned earlier.
I hope this helps!
