A 75 kg person is standing at the very end of a 6.0 meter long stationary raft with a mass of 225 kg that is floating frictionlessly on the water. If the person then walks with a constant velocity of 1.0 m/s all the way to the other end of the raft, how far will the raft move, and what will be the average velocity of the raft during that movement (as observed by a stationary person on shore)?

A young girl (mass = 35.0 kg) is standing on a raft floating on a pond (initial speed = 0). The raft's length is 4.00 m; it is made of wood (density = 700 kg/m3) and has a mass of 267 kg. The density of water is 1000 kg/m3.             a.         Before the girl gets on the raft, what fraction of its volume is below the water?             b.         The girl and the raft were initially at rest (relative to the water), with the...

A lumberjack (mass = 103 kg) is standing at rest on one end of a floating log (mass = 245 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +2.47 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. Neglect any friction and resistance between the logs and the water. (a) What is the velocity of the first log justbefore...

A lumberjack (mass = 112 kg) is standing at rest on one end of a floating log (mass = 250 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a speed of 3.0 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. What is the speed of the first log relative to the second log when the lumberjack comes to rest with respect...

A person with mass mp = 75 kg stands on a spinning platform disk with a radius of R = 1.65 m and mass md = 187 kg. The disk is initially spinning at ω = 1.4 rad/s. The person then walks 2/3 of the way toward the center of the disk (ending 0.55 m from the center). 1) What is the total moment of inertia of the system about the center of the disk when the person stands on...

Ethan, whose mass is 80 kg, stands at one end of a very long, stationary wheeled cart that has a mass of 500 kg. He then starts sprinting toward the other end of the cart. He soon reaches his top speed of 8.0 m/s, measured relative to the cart. What is the cart’s speed when Ethan reaches top speed? Express your answer with the appropriate units.

You are on a 20 meter long boat, it weights 1000 kg, and you weigh 100 kg. Consider the system of you and the boat together. (Assume the boat slides on the water without friction, the boat’s center of mass is at its center, and your center of mass is the same height as the boat’s center of mass). a)   If you are at one end of the boat, how far from the center of the boat is the system’s...

Superman (120.0 kg), Aquaman (100.0 kg) and Batman (90.0 kg) are all standing on a 12.00 m long thin log (5.00 kg) whose left end sits at rest in the water right next to shore (taken to be x = 0), arguing over who has the best movie. Wonder Woman stands quietly on the shore. Superman is 2.00 m from the left end of the log. Aquaman is 1.00 m to the right of Superman and Batman is 4.00 m...

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
