Question
In a cheerleading competition, the 65.0 kg cheerleader is tossed vertically upward with a speed of 3.75 m/s. a. What is the change in momentum of the cheerleader from the momentum she was tossed up to just before being caught assuming she was caught at the same height as she was thrown? b. What is her change in momentum if she was caught 0.52 m below the point of release?

- how to do?arrow_forwardYou drop a steel ball and a clay ball, both of the same mass, from the same distance. The steel ball strikes the ground and rebounds with almost the same speed. The clay ball strikes the ground and sticks. Assume the collisions occur over roughly the same amount of time. Which ball exerted a greater force on the ground? Select the correct answer with the best explanation. A. The two exert the same force. Since they collide with the same initial momentum, they will exert thesame force.B. The clay ball exerts the greater force. Since it starts with some momentum and ends with no momen- tum, it undergoes a greater change in momentum than the steel ball, which rebounds with the same momentum (no change).C. The clay ball exerts the greater force. All of its energy is transferred to the floor, whereas the steelball rebounds with the same kinetic energy, doing no work on the floor.D. The steel ball exerts the greater force. Since it starts with some momentum and it reverses the direction of…arrow_forwardA pitcher throws a baseball of mass m = 0.150m=0.150 kg with a velocity of 43.7 m/s.

- The ballistic pendulum is a device to measure the speed of a bullet using conservation of energy and momentum. A 20 g bullet is fired horizontally into a 1.1 kg wood block hanging from a 1.2-m-long string. The bullet embeds itself into the block, and the block then swings out to an angle of 35°. A. How high does the block of wood go relative to its initial height when its hanging straight down? B. What is the increase in gravitational potential energy of the wood block at its maximum height? C. Use conservation of energy to determine the speed of the block just after the bullet strikes it. D. Use conservation of momentum to determine the speed of the bullet right before it strikes the block.arrow_forwardA mouse who weighs 40g is riding on a 0.25kg frictionless, motorless toy car. The car is coasting at 0.3m/s when the mouse decides to jump off. The mouse wants to jump off so that the car ends up not moving relative to the ground. Draw three momentum bar charts, one for the mouse, one for the car and one for the combined system showing how this could work. What is the speed of the mouse right after he jumps? State any equations that you use.arrow_forwardQuestions 1.-4. refer to a head-on collision between two balls with the following initial values: Before Collision m2 V Ix 3.5 kg 4.5 kg 5.0 m/s -2.0 m/s 1. What is the total momentum (in kg m/s) of the system? 2. If the two balls stick together, what is their common speed (in m/s) after they collide? 3. How much kinetic energy (in joules, positive number) was lost in this collision? 4. If the two balls do not stick together, and the first ball moves at vịx = -1 m/s after they collide, what is the speed (in m/s) of the second ball?arrow_forward
