Question 3

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

Explanation:

Answer:

1.8 -ve

Explanation:

initial velocity = 54m/s

final velocity = 36m/s

acceleration = final velocity - initial velocity/time

time given = 10 sec

acceleration = 36 m/s - 54 m/s / 10 sec

acceleration = -18/10

acceleration = -1.8
