Question

A truck travelling at 54 km/h is slow down to 36 km/h in 10 sec. Find the retardation(km/h)​

Answer 1

Answer:

retardation is 1.8 (neg)

Step-by-step explanation:

The truck is travelling with a final velocity of u=36m/s.

acceleration=V-U/T.

given time =10s.

so. 36-54/10

=-18/10

=-1.8

so. the retardation is 1.8 negative.
