Question

A truck travelling at 54km/h slows down to 36km/h in 10sec. Find the retardation​

Answer 1

Answer:

The Retardation rate is 1.8 m/s².

Explanation:

Let the initial velocity be u.

Let the total velocity be v.

Let the time be t.

So,

u = 54 km/hr

v = 36 km/hr

t = 10 s

Retardation = (u-v)/t

= (54-36)/10 m/s²

= 18/10 m/s²

= 1.8 m/s²

Hope this helps.
