A girl is standing on a raft of mass 48 kg moving at 1.5m/s west. The girl then walks on the raft with a net velocity of 1.0 m/s at 30o north of west. As the girl walks, the net velocity of the raft is 2.0 m/s at 10.5o south of west. Solve for the girls mass using components.
A lumberjack (mass = 98 kg) is standing at rest on one end of a floating log (mass = 215 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +4.0 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 just...
A lumberjack (mass = 98 kg) is standing at rest on one end of a floating log (mass = 260 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +3.5 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 just before the lumberjack jumps...
A lumberjack (mass = 98 kg) is standing at rest on one end of a floating log (mass = 275 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +3.5 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 just...
A lumberjack (mass 98 kg) is standing at rest on one end of a floating log (mass = 290 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +3.9 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 just before...
A 45.0 kg girl is standing on a 159 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.38 m/s relative to the plank. (a) What is her velocity relative to the surface of ice? 1 m/s (b) What is the velocity of the plank relative to the surface of ice? 2 m/s
A lumberjack (mass = 94.4 kg) is standing at rest on one end of a floating log (mass = 279 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +2.64 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 (again...
A 44.8-kg girl is standing on a 159-kg plank. Both originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity of 1.48î m/s relative to the plank. (a) What is the velocity of the plank relative to the ice surface? (b) What is the girl's velocity relative to the ice surface? î m/s
A 48.8 kg girl is standing on a 136 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.59 m/s relative to the plank. What is her velocity relative to the ice surface? What is the velocity of the plank relative to the ice surface?
A 40.7 kg girl is standing on a 151 kg plank. Both are originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity of 1.56 m/s x̂ relative to the plank. (a) What is the velocity of the plank relative to the ice surface? (b) What is the girl's velocity relative to the ice surface?
