A tennis ball is struck and departs from the racket horizontally with a speed of 29.7 m/s. The ball hits the court at a horizontal distance of 20.4 m from the racket. How far above the court is the tennis ball when it leaves the racket?

Drag each item into the proper state of matter category.

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
