A ball of mass \(1\ kg\) moving with a speed of \(10\ ms^{-1}\) rebounds after a perfect elastic collision with the floor. Calculate the change in linear momentum of the ball.
Mass of a ball (\(m\)) \(=\) \(1\ kg\)
Velocity of the ball before collision (\(u\)) \(=\) \(ms^{-1}\)
Velocity of the ball after collision (\(v\)) \(=\) \(ms^{-1}\)
The formula to calculate the change in linear momentum is
On substituting the known values, we get
\(Change\ in\ linear\ momentum\ of\ the\ ball\) \(=\) \(kg\ ms^{-1}\)
