Question

A boy on a bicycle accelerates uniformly at 4.0 m/s^2 from an initial velocity of 4.0 m/s to 9.5 m/s. How long(time) does it take him to reach his final

velocity (Vf))?

Answer 1

1.125 seconds

Explanation:

As we know that acceleration = Final velocity- Initial Velocity

Time taken

a=v-u

t

t=v-u

a

In this case, Time taken=
`(9.5-4)/(4)`

`=(4.5)/(4)\\=1.125` seconds
