You are playing Hot Rod toy cars with your nephew and niece. Your nephew wanted to show off how fast he could launch a Hot Rod off the dining table 1.1 m above the floor by thrusting the car forward very fast but was no match against your niece who compensated slight lack of speed by pushing the car straight forward reaching a speed of 3.0 m/s at the edge of the table top when she let go of it. How far did her car land horizontally from the edge of the table?
A basketball is thrown at 45° to the horizontal. The hoop is located 4.3 m away horizontally at a height of 0.9 m above the point of release. What is the required initial speed?

- A friend of yours has a one story house with a pool in the backyard. Someone gets the bright idea to jump from the roof of the house into the deep end of the pool. a) If the roof of the house is 16 ft tall and the horizontal distance between the edge of the house and the pool is 10 ft, what would the jumper's minimum velocity need to be to land in the pool? b) Let's assume your friend can jump with an initial horizontal velocity of 15 ft/s.

- A minigolf ball is on a perfectly horizontal surface, x = 2 m away from the center of the hole. There is a small obstacle in the way, so the ball cannot simply roll to the hole –it must go up in the air. The player is able to shoot with an initial speed v0 = 7 m/s. The ball can be launched at TWO possible angles with the horizontal for the ball to get in the hole. We want your to find these two angles.arrow_forwardA plate slides off the edge of a kitchen table with an initial velocity of 3 m/s horizontally. The height of the tabletop above the ground is 4.0 m.
