Question

A car mass 1000kg and a bus of mass 8000kg are moving with a same velocity of 36km/h.Find the forve to stop both in 5 sec​

Answer 1

Explanation:

Initial velocity = 36km/hr = 10m/s

Finial velocity = 0m/s

Time = 5sec

v = u + at

0 = 10+a5

a = -2m/s^2

The force need to stop the bus = ma

= 8000×2

= 16000N

The force need to stop the car = ma

= 1000×2

= 2000N

Hope this helps u!
