Book Free DemoA stone of \(1\ kg\) is thrown with a velocity of \(20\ m\ s^{-1}\) across the frozen surface of a lake and comes to rest after travelling a distance of \(50\ m\\). What is the force of friction between the stone and the ice?
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 stone\(=\) \(N\)
