Question

An object starts from rest and moves with a constant acceleration. It travels a distance of 800m in

40s. Find the acceleration. Find the force acting on it if its mass is 500Kg​

Answer 1

Step-by-step explanation:

Given data:

Mass of stone(m)=7000 kg

Distance(S)=400 meter

Time(t)=20 second

1) We have to find the acceleration of the truck

So from the equation of motion S=ut+
