A helicopter winches up an injured man from a boat. The man plus equipment has a mass of 111 kilogram. If the height of the lift is 97 meter and it is carried out at a uniform rate over 75 sec, find the power expended by the helicopter's winch motor? Suppose that the engine is 64 percent efficient.
The needle of a sewing machine moves up and down in the same hermonic motion its driving force comes from a rotating wheel that is powered by an electric motor. how do you imagine that theup-and-down needle comapres with the period of the rotating..
A dentist's drill starts from rest. After 3.30 s of constant angular acceleration it turns at a rate of 2.0 x 10^4 rev/min. Find the drill's angular acceleration
Some bacteria are propelled by motors that spin hair-like flagella. A typical bacterial motor turning at a constant angular velocityhas a radius of 1.9x10-8m, and a tangential speed at therim of 2.9x10-5 m/s.
