Question

a truck starts from rest and Rolls down a hill with constant acceleration it travels a distance of 400 m in 20 seconds calculate the acceleration and the force acting on it if its mass is 7 metric tons

Answer 1

the answer is 14000 N

Answer 2

u=0
s=400m
t=20sec
s=ut+1/2at^2
a=2m/s^2

m=7000kg
F=ma
F=14000N
