1)A 0.0200kg bullet is shot horizontally and collides with a 2.07kg block ofwood. The bullet embeds in the block: and the block slides along a horizontal surface for 1.70 m. If the coefcient of kinetic friction between the block and surface is 0.400, what was the original speed of the bullet? In rm's 2] A at, circular metal disk of uniform thickness has a radius of 4.00 cm. A hole is drilled in the disk that is 2.00 cm in radius. The hole is tangent to one side of the disk. Where r2400 Where r = 4.00. a}Where is the xcomponent of the GM of the disk now that the hole has been drilled? In cm 3) A 0.15ttkg baseball traveling in a horizontal direction with a speed of 18.0 rnfs hits a bat and is popped straight up with a speed of 17.0 rrv's a} . What is the magnitude of the change in momentum of the baseball? In kg-rrv's b}At what angle with respect to the horizontal does the change in momentum of the baseball occur? I above the horizontal direction opposite v>i c)lf the bat was in contact with the ball for 50.0 mls, what was the average force of the bat on the ball? Enter a positive answer if the average force is in the direction of momentum change and enter a negative answer if the average force is opposite to the direction of momentum change. In Newton 4} A 01ng ball collides elastically with a 0.300kg ball that is at rest. The 0.100kg ball was traveling in the positive x direction at 5.80 rrvs betore the collision. a} What is the velocity of the 0.300kg ball aerthe collision? If the velocity is in the )Hiirection, enter a negative value. In rrv's b] What is the velocity of the 0.100-kg ball afterthe collision? If it is in the xdirection, enter a negative value. In nits 4)A tennis ball of mass 0.0561 kg is served. It strikes the ground with a velocity of 54.0 WS (120 mii'h) at an angle of 220 below the horizontal. Just after the bounce it is moving at 53.0 ms at an angle of 18.0\" above the horizontal. a) If the interaction with the ground lasts 0.0630 s, what is the magnitude of the average force exerted by the ground on the ball? In Newton
