Presentation transcript:

Question #1 A ball rolls off a desk at a speed of 2.6 m/s and lands 0.65 seconds later. a) How high is the desk? b) What is the speed and angle of impact?

Question #2 A slingshot is used to launch a stone horizontally from the top of a 15.0 meter cliff. The stone lands 32.0 meters away. a) At what speed was the stone launched? b) What is the speed and angle of impact?

Question #3 A canon ball is fired horizontally from a cliff has a final velocity directed at 50o with the horizontal when it hits the ground 4.0 seconds later. a) How high is the cliff? b) How far from the base of the cliff does the canon ball land?

Question #4 A ball rolls with a speed of 4.6 m/s across a level table that is 1.3 m above the floor. Upon reaching the edge of the table, it follows a parabolic path to the floor. How far along the floor is the landing spot from the table?

Question #5 What is the acceleration of a projectile at the peak of its parabolic path?

Question #6 A diver running at 5.7 m/s dives out horizontally from the edge of a cliff and reaches the water below 2.5 seconds later. a) How high is the cliff? b) How far from the base of the cliff did the diver hit the water?

Question #7 A football is kicked at 32.0o to the horizontal at 18.0 m/s from the player’s hand at 1.20 m from the ground. How far did the football travel before hitting the ground?

Question #8 Two ball players are warming up together. The first ball player throws a ball in the air at an angle of 20o to his partner, who catches it at the exact height in which it was thrown. The ball is thrown with an initial velocity of 20 m/s. a) How long is the ball in the air for? b) How far away is the other ball player?

Question #9 A rock is projected off a cliff that is 15.3 m high. The rock is launched with a velocity of 5.2 m/s at an angle of 37o above the horizontal. a) How long is it in the air for? b) How far from the base of the cliff does the rock land?

Question #10 A catapult is detonated and launches a projectile with a velocity of 16.8 m/s at an angle of 21o. At 0.75 seconds a) how high above the ground is the projectile? b) how far is the projectile in the horizontal?

Question #11 A tennis ball is hit with a speed of 70 m/s at an angle of 30 degrees. If it lands at the same level as the one it was hit from, a) Determine how far horizontally the ball travels.

Question #12 A ball is thrown horizontally off a 40 meter high cliff and it lands 40 meters away from the base of the cliff. a) Determine the speed with which the ball was thrown. b) Determine the final velocity and the angle of impact.

Question #13 What is Mr. Boling's drink that he gets at Starbucks?

Question #14 A softball is hit with a speed of 70 m/s at an angle of 30 degrees with the ground. Does the ball make it over a fence that is 100 meters away and 3 meters high? (answer must include the height of the projectile at that point)

Question #15 How many ties does Mr. Boling own?

Question #16 A golf ball travels 200 meters horizontally and reaches a maximum height of 20 meters. a) Determine the ball's initial horizontal and initial vertical velocity.
