- Consider the two pucks shown in the figure. As they move towards each other, the momentum of each puck is equal in magnitude and opposite in direction. Given that v; oreen = 12.0 m/s, and mblue is 25.0% greater than mareen, what are the final speeds of each puck (in m/s), if - the kinetic energy of the system is converted to internal energy? 30.0 30.0 Vgreen m/s V blue m/sThe 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.Physics A catcher in a baseball game stops a pitched ball originally moving at 49.0 m/s49.0 m/s in the positive direction at the moment it first comes in contact with the catcher’s glove.
