A300kg motorboat is turned off as it approaches a dock and coasts towards it at .5 m/s. isaac, whose mass is 62 kg jumps off the front of the boat with a speed of 3m/s relative to the boat. what is the velocity of the boat after isaac jumps?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.

Which sections of the heating curve illustrate this process?

What about a rubber band, can it change its shape? is it a solid?
