... Impulse equals a change in momentum. Impulse = force x time Impulse = 120N x 0.25s = 30Ns Santi tries to stop a free kick from Leo. The soccer ball has a mass of 0.8kg. The speed of the ball is 30.2 m/s by the time it reaches the goal. What is its momentum? P=mv or momentum = mass x velocity Momentu ...
