A car stops in 130 m. If it has an acceleration of -5 m/s2 what was the cars starting velocity? after
Variables:
Equation and Solve:

An automobile of mass 2000 kg moving at 30 m/s is braked suddenly with a constant braking force of 10000 n. how far does the car travel before stopping?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

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.
