A cannonball is shot from the edge of a 20-m-high vertical cliff with an initial speed of 50 m/s at an angle of 400 above the horizontal. Assume that the ground at the bottom of the cliff is flat and level. What will be the velocity of the cannonball in rectangular components (vx, Vy) when it hits the bottom? (See the diagram below.) Assume that g = 9.8 m/s? Vo = 50 m/s Vo 400 Cannonball 20 m a. (42.0 m/s, 21.0 m/s) b. (38.3 m/s, 37.7 m/s) C. (25.0 m/s, 12.5 m/s) d. (34.8 m/s, 17.1 m/s) O e. (40.0 m/s, 30.5 m/s)

A student launches a small rocket which starts from rest at ground level. At a height h=1.04km, the rocket reaches a speed of vf=391m/s. At that height, the rocket runs out of fuel, so there is no longer any thrust propelling it. Take the positive direction to be upward. After the rocket's engine turns off at a height of h=1.04kmℎ=1.04km, it continues to move upward due to the velocity that it reached. Calculate the maximum height, in meters above ground level, that the rocket reaches.
During a summer vacation, a group of professional football players were having a contest to see who could jump the farthest off a dock into the lake. One player’s horizontal distance at splashdown was 3.65 m from the edge of the dock. If the surface of the dock sits 1.20 m above the water surface and the player left the dock with a 0.0o launch angle, what was the player’s speed when he left the dock?
