Abicycle is traveling north at 5.0 m/s. the mass of the wheel, 2.0 kg, is uniformly distributed along the rim, which has a radius of 20 cm. what are the magnitude and direction of the angular momentum of the wheel about its axle?

To do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out?

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.

Aforce of 8,480 n is applied to a chart to accelerate it at a rate of 26.5 m/s2. what is the mass of the cart?
