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}
