4. A truck starting from rest moves down a hill witha constant acceleration. If it covers a distance of300 m in 10 s, find its acceleration. Also find theforce acting on it if its mass is 8000 kg.

Answer»

Acceleration = change in velocity / change in time= (v - vo) / (t - to)

Average Velocity= Change in displacement/ Total time= 300/10 = 30 m/s

Acceleration = (30 - 0)/(10 - 0) = 3 m/s^2

Force acting on truck= mass*acceleration = 8000*3 = 24000 N
