A car of mass m = 1635 kg is pushed off a cliff of height h = 23 m. If the car lands a distance of 9 m from the base of the cliff, what was the kinetic energy of the car the instant after it left the cliff?
Calculate the velocity of a satellite moving in a stable circular orbit about the Earth at a height of 2600 km.
a 15 ft ladder is palced against a wall such that its base is 9 ft away from the wall. if the base of the ladder is moved to 6 ft away from the wall, by about how much will the top of the ladder move up the wall?

A ramp leading up to a loading platform is 3 m long and 1 m high at its highest point. If the friction is ignored, what work is needed to slide a 600-kg crate up the ramp at a constant speed? a) 2.00 *10^2 J b) 5.89 *10^2 J c) 1.80 *10^3 J d) 5.88 *10^3 J I believe the answer ...
In this problem they show a diagram of a pulley system with an inclined plane (25 degree incline). There is a box called m1=47kg resting on the incline plane and m1=35kg hanging on the vertical line. The question reads: The coefficient of friction between m1 and the surfvace o...
