Question

a vehicle of mass 120kg is moving with a velocity 25m/s.what force should be applied on the vehicle to stop it in 5sec

Answer 1

We know that a = (v - u)/ t

Here , u = 25 m/s
v = 0 since the vehicle comes to stop

t = 5 s

So , a = 25/5 = 5 m/s^2

Now, F = ma
F = 120 x 5
F = 600 N

Hope This Helps You!

Answer 2

a = (v - u)/ t

u = 25 m/s
v = 0 since the vehicle comes to stop

t = 5s

Therefore,

a = 25/5
= 5 m/s^2

Now, F = ma
F = 120 x 5
F = 600 N
