1. A 64.80 g ball was fired into a 185.00 g ballisticpendulum hanging 7.10 cm from the base of the ballistic device. Theball was trapped in the pendulum bob, and the impact caused thependulum to swing to a height of 13.70 cm from the base. Calculatethe a) velocity of the ball and pendulum after impact b) initialvelocity of the ball before impact c) the total momentum of theball and pendulum before impact d) the total momentum of the balland pendulum after impact   e) What type of collision isshown in the problem?

2. A 1.50 kg carpenter's tool fell from the roof of abuilding 12.0 m high. Show that the total mechanical energy (sum ofPE and KE) a) before falling b) 1.5 s after it has fallen and c)when it reach the ground are equal.

3. A 0.280 kg volleyball approaches a playerhorizontally with a speed of 15.0 m/s. The player strikes the ballwith her fist and causes the ball to move in opposite directionwith a speed of 22.0 m/s. a) What impulse is delivered to the ballby the player? b) If the player's fist is in contact with the ballfor 0.0600 s, find the magnitude of the average force exerted onthe player's fist. (Remember that change in momentum = impulse andvelocity is a vector quantity)

4. A 2.0 kg body is tied at the end of a string andwhirled in a horizontal circle of radius 1.2 m at 3revolutions per second. Determine the a) speed b) acceleration c)pull of the string on the body d) pull of the body on thestring

5. A weight lifter lifts a 350 N set of weights fromground level to a position over his head , a vertical distance of2.00 m. How much work does the weight lifter do , assuming he movesthe weights at constant speed?
