**Question 4:** Larry has a mass of 80 kg and runs across the front of the classroom with a speed of 4 m/s and jumps onto a giant skateboard. The skateboard is initially at rest and has a mass equal to Larry's. If friction with the floor is negligible, what is the speed of Larry and the skateboard after he jumps on board?

Problem 5: A 1.8 kg falcon catches a 0.65 kg dove from behind in midair. What is the speed of the pair of birds right after the catch if the falcon's initial speed was 28 m/s, the dove's initial speed was 7 m/s, and they were moving in the same direction?
answer is vf= 1.0 m/s.
Gayle runs at a speed of 4.15 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 45.0 kg, the sled has a mass of 5.05 kg and her brother has a mass of 30.0 kg. m/s
A rock (rock 1) is flying in the sky towards another rock, rock 2. Rock 1 has a mass of 60 kg, and Rock 2 has a mass of 10 kg. Rock 1 is in the sky with a speed of 25 m/s towards Rock 2, and rock 2 is movingtowards Rock 1 in the opposite direction with a speed of 35 m/s. If the two rocks stick together, what is their final velocity? Ignore air resistance and gravity. Is there a change in the kinetic energy of the system? If so, what is it?
A package of mass m is released from rest at a warehouse loading dock and slides down the h = 2.0 m high, frictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 2m2m, from the bottom of the chute. Suppose the packages stick together. What is their common speed after the collision? Suppose the collision between the packages is perfectly elastic. To what height does the package of 2m mass mm rebound?
A lumberjack is standing on a log floating on a lake. She starts from rest, then runs along the log to the end, when she jumps from the first log onto a second. After landing safely on the second log, she slows down and ends up standing on the second log. Both logs both have masses of 150 kg each and the mass of the lumberjack is 70 kg. The lumberjack reaches a speed of 7.0 m/s relative to the shore during her jump. What are the speeds of the two logs and of the lumberjack after she has stopped on the second log? You may assume the drag of the water on the logs is very small.

Gayle runs at a speed of 3.60 m/s and dives on a sled, initially at rest on the top of a frictionless snow - covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 46.5 kg, the sled has a mass of 5.10 kg and her brother has a mass of 30.0 kg.
A red cart of mass 270g and a blue cart of mass 690 g are at rest on a level track. They are pushed apart by an expanding spring giving the red cart a speed 1.01 m/s. This is a two part problem.

Problem-3: A ball of mass 200 gram strikes a wall perpendicular to its surface at a speed of 10 m/s and rebounds back at the speed of 5 m/s. It is in contact with the wall for 2 milli-sec. Find the average force exerted by the wall on the ball.
A 12.0 g wad of sticky clay is thrown horizontally at a 100.0 g block of wood initially at rest on a horizontal surface. The clay sticks to the block and together they slide 7.50 m before coming to rest. If the coefficient of kinetic friction between the black and the surface is 0.650, what was the speed of the clay before impact?
a 600 gram banana sliding north on a frictionless table at 2.5 meters per second bounces of a 400 gram kiwi fruit that is initially at rest , after colliding the banana continues moving north at 0.5 meters per second. At the North edge of the track is a frictionless inclined ramp which the kiwi fruit slides up to then the kiwi comes back down the ramp , without losing energy , and will now be moving south , the kiwi will catch up and hit the banana again. How much momentum did the kiwi have just before the sticky collision ? how much just after ? how much did the kiwis momentum change ?
