1. Two crickets, Chirpy and Milada, jump from the top of a vertical cliff. Chirpy just drops from a vertical cliff with a height of 350 m, while Milada jumps horizontally with an initial speed of 8.0 m/s. How far from the base of the cliff will Milada hit the ground? [67.6 m]

2. A ball is given an initial velocity of 30.0 m/s at an angle of 60.0o with respect to the horizontal. What are the horizontal and vertical displacements after 5.00 s? [75.0 m, 7.40 m]

3. A soccer player kicks the ball toward a goal that is 16.8 m in front of him. The ball leaves his foot at a speed of 16.0 m/s and an angle of 28.0┬░ above the ground. Find the speed of the ball when the goalie catches it in front of the net. [14.7 m/s]
