Numerical Problem:
The graph represents the variation of velocity with time for a ball of mass \(50\ g\) moving on a concrete floor. Calculate the ball’s acceleration and the frictional force applied by the floor.

v-t graph
The acceleration (\(a\)) is found using,
From the Newton's second law, We know that,
Acceleration\(=\) \(m\ s^{-2}\)
Frictional force of the floor on the ball \(=\) \(N\)
