1) Identical twins Kate and Karen are rowing their boat on a hot Summer afternoon when they decide to go for a swim. Kate, whose mass is 40 kilograms, jumps off the front of the boat at a speed of 3.00 m/sec. Karen jumps off the back at a speed of 4.00 n/sec. If the 70 kilogram rowboat is moving at 1.00 m/s before the girls jump, what is the speed of the rowboat after the girls jump? m/sec j) A 0. 10 kilogram piece of modeling clay is tossed at a motionless 0.10 kilogram block of wood and sticks. The block slides across a frictionless table at 13.7 m/sec. L. Atwhat speed was the clay tossed? i'm/sec U. The clay is replaced with a "bouncy" ball tossed with the same speed. The bouncy ball rebounds from the wooden block at the same speed as in part I. What effect does this have on the wooden block? O There is no momentum difference upon impact with the block between the clay and bouncy ball since they are thrown at the same speed and have the same mass. The wooden block travels at a slower speed. The wooden block travels at a faster speed. Why ? O Both clay and bouncy balls undergo the same change in momentum upon collision. The bouncy ball undergoes a greater change in momentum upon collision. The clay undergoes a greater change in momentum upon collision
