Question

A train of mass 240 000 kg is travelling at a speed of 60 m / s. The brakes are applied and it decelerates for 10 minutes until it comes to rest. Calculate the average resultant force?

Answer 1

Answer:

v=u+at

v=0m/s,u=60m/s,t=10min or 600sec

0=60+600a

a= (-1/10)m/s^2 or 0.1m/s^2

NOW

f=MA

f=2,40,000×0.1. (m=2,40,000) given

f=24,000N

thankyou!
