1.) A ball is thrown off a 50-meter cliff with an initial velocity of 20 meters per second at an angle of 30 degrees above the horizontal. What is the velocity of the horizontal component of the ball's motion? 2.) A force of 100N acts on a 80kg body for 4 seconds. Find the impulse produced by the force and the resulting change in momentum of the body. Find Impulse and momentum

Explanation:
1.) The velocity of the horizontal component is 17.3 m/s. 2.) Impulse is 400 Ns and momentum change is 3200 kg*m/s.
