1. A helicopter is lifting two crates simultaneously. Crate A, with a mass ma, is attached to the helicopter by a light cable (cable #1). Crate B, with a mass me, hangs below crate A and is attached to crate A by a second light cable (cable #2). The cables are NOT connected. The helicopter accelerates upward with an acceleration of magnitude a. Ignore all frictional effects. Let T be the tension in cable #1 and Tbe the tension in...

A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter. An 890-kg helicopter rises from rest to a speed of 9.0 m/s in a time of 4.5 s. During this time it climbs to a height of 8.4 m. What is the average power generated by the lifting force?

The crane shown in the figure is lifting a 463-kg crate upward with an acceleration of 2.60 m/s2. The cable from the crate passes over a solid cylindrical pulley at the top of the boom. The pulley has a mass of 111 kg. The cable is then wound onto a hollow cylindrical drum that is mounted on the deck of the crane. The mass of the drum is 124 kg, and its radius (the same as that of the pulley)...
