Question

is moving at a velocity 25 metre second is brought to rest by applying the brakes of produce inform radiation of 0.5 metre per second square calculate the velocity of train after 10 seconds if the mass of the train is 2000 kg g then the calculate the force required to the train​

Answer 1

Explanation:

v=u+at

u=25 a=-0.5 t=10

v=20 m/s

F=ma

f=2000×0.5=1000N
