Question

truck starts from rest and rolls down a Hill with constant acceleration it travels a distance of 400 metre in 20 seconds find its acceleration find the force acting on it mass of metric tones​

Answer 1

Answer:

Explanation:

using s=ut+1/2at^2

s=1/2at^2

substituting we get a=2m/sec^2

therefore force=ma(newton first law of motion)

f=1000kg.2m/sec^2

f=2000kgm/sec^2

f=2000newton=2.10^8dynes
