Question

A bus is moving with an intial velocity U m/s after applying brakes its retaralation is 0.5 m/s and its stopped after 12.5 find the intital velocity U and distance travelled by the bus after applying breaks​

Answer 1

Answer:

Final velocity v=0

Using v=u+at

So, 0=u+(−0.5)×12

⟹ u=6 m/s

Using, v

2

−u

2

=2aS

Or, 0−6

2

=2×(−0.5)×S

⟹ S=36 m
