1.) Consider the ballistics pendulum experiment. If M=1kg and m=0.1kg, and the velocity of the bob-ball system right after the collision is Vf=2m/s, what was the initial velocity of the ball before it hit the bob?

2.) A ball is fired horizontally from a height of 1m above the ground, and travels a range of 2.1m before it hits the ground. What is the initial speed of the ball?
