A body was moving with a velocity 60km/hour. It is brought to rest by applying a force of 200newton.Find the mass of body in5sec

I'm assuming the body is brought to rest in 5 sec.

Vo = 60km/h = 60,000m/3600s. = 16.67 m/s.

V = Vo + a*t.
0 = 16.67 + a*5,
a = -3.33 m/s^2.

Fap = M*a.
=200 = M*(-3.33),
M = 60.0 kg.

To find the mass of the body, we need to use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Given:
Velocity (v) = 60 km/hour
Force (F) = 200 Newton
Time (t) = 5 seconds

First, we need to convert the velocity from km/h to m/s:
1 km/h = 1000 m/3600 s
Therefore, v = 60 km/hour = (60 * 1000) / 3600 = 16.67 m/s

Next, we can calculate the acceleration using the formula:
Force (F) = Mass (m) * Acceleration (a)
Rearranging the formula, we get:
Acceleration (a) = Force (F) / Mass (m)

Since the body comes to rest, the final velocity (v) is 0. Therefore, we can use the following equation to calculate the acceleration:
v^2 = u^2 + 2as
Where u is the initial velocity, v is the final velocity, a is the acceleration, and s is the distance traveled.

Since the body comes to rest, the final velocity (v) is 0. The initial velocity (u) is 16.67 m/s, and the time (t) is 5 seconds (which gives us the distance traveled).

0 = (16.67)^2 + 2 * a * s

Since the body is brought to rest by applying a force, the acceleration (a) can be calculated using Newton's second law of motion:
200 = m * a

Now, we have two equations:

0 = (16.67)^2 + 2 * a * s
200 = m * a

To find the mass (m), we need to solve these equations simultaneously.

First, we solve the equation 200 = m * a for acceleration (a):
a = 200 / m

Substituting this value of a into the first equation:

0 = (16.67)^2 + 2 * (200 / m) * s

Now, we can solve this equation for the mass (m).

Note: To find a numerical value for the mass, we also need to know the distance traveled (s) in order to solve the equation.
