006 (part 1 of 3) 10.0 points An Alaskan rescue plane traveling 44 m/s
drops a package of emergency rations from
a height of 160 m to a stranded party of
explorers.
The acceleration of gravity is 9.8 m/s?.
Where does the package strike the ground
relative to the point directly below where it
was released?
Answer in units of m.

Which type of wave can travel without a medium

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
