Question

A bus accelerates uniformly from 108km/h to 54 km/h in 20 seconds. Calculate Retardation​

Answer 1

Answer:

Explanation:

108km/h=108x5/18  =30m/s.

54km/h=54x5/18 =  15m/s.

v=15m/s, u=30m/s , t=20sec

∴v-u/t=a

=15-30/20

=-0.75m/sec2. (as its retardation).

Hope this helps please tell.
