- Joe and Bill throw identical balls vertically upward. Joe throws his ball with an initial speed twice as much as the initial speed of Bill's ball. If there is no air resistance, the maximum height of Joe's ball will be O eight times that of Bill's ball. O two times that of Bill's ball. O equal to that of Bill's ball. None of the given choices O four times that of Bill's ball.A bartender slides a beer mug at 1.0 m/s towards a customer at the end of a frictionless bar that is 2.0 m tall. The customer makes a grab for the mug and misses, and the mug sails off the end of the bar. (a) How far away from the end of the bar does the mug hit the floor? (b) What are the speed and direction of the mug at impact? speed=?m/s direction=?° below the horizontal1. Given velocities of two identical billiard balls just before impact, determine post- impact velocity of each ball. COR = 0.92. Ignore effects of friction. V82 %3D A 35° 75° 30 ft/s 40 ft/s
- Here’s an interesting challenge you can give to a friend. Hold a $1 (or larger!) bill by an upper corner. Have a friend prepare to pinch a lower corner, putting her fingers near but not touching the bill. Tell her to try to catch the bill when you drop it by simply closing her fingers. This seems like it should be easy, but it’s not. After she sees that you have released the bill, it will take her about 0.25 s to react and close her fingers—which is not fast enough to catch the bill. How much time does it take for the bill to fall beyond her grasp? The length of a bill is 16 cm.Two identical objects with the same initial speed collide and stick together.

- A firecracker moves vertically upward and after reaching the highest point in its vertical trajectory, it starts falling down. After it falls down by 17.7 meters in air it cracks into two identical pieces. One of the pieces shoots off horizontally with 11.8 m/s speed. What would be the magnitude of the velocity of the other piece right after they split? Enter your answer in m/s. On your paper, show both your calculation for the magnitude and also the direction of the velocity vector of the second piece. Show your work in detail including your physics- based reasoning.phyProfessional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. a) Calculate the velocity of the ball just after it is struck b) What is the 0.0450 kg ball's change in momentum?
