Problem 2.1:
What is the impulse of a force of 10 N acting on a ball for 2 seconds?
[Solution]Problem 2.2:
Consider the last problem. The ball weighs 2 kg and is initially at
rest. What is the velocity of the ball after the force has acted on it?
[Solution]Problem 2.3:
A particle has linear momentum of 10 kg-m/s, and a kinetic energy of 25
J. What is the mass of the particle?
[Solution]Problem 2.4:
A 2 kg bouncy ball is dropped from a height of 10 meters, hits the floor and
returns to its original height. What was the change in momentum of the ball
upon impact with the floor? What was the impulse provided by the floor?
[Solution]Problem 2.5:
A ball of 2 kg is thrown straight up into the air with an initial velocity
of 10 m/s. Using the impulse-momentum theorem, calculate the time of flight of the ball.
