A truck starts from rest and rolls down a hill with a constant acceleration. It travels a distance of \(400\ m\) in \(20\ s\). Find its acceleration. Find the force acting on it if it’s mass is \(7\ tonnes\) (Hint: 1 tonne = 1000 kg.)
From the Equation of motion, We know that,
From the Newton's second law, We know that,
Acceleration \(=\) \(m\ s^{-2}\)
Force acting on the truck\(=\) \(N\)
