A father pushes horizontally on his daughters sled to move it up a snowy incline. If the sled moves up the hill with a constant velocity, how much work is done by the father in moving it from the bottom to the top of the hill? The hill is at an angle of 15 degrees and it is 3.6 meters high at...

A space ship of mass 5.00 × 18*4 kg is traveling at a speed 1.15 × 10*4 m/s in outer space. Except for the force generated by its own engine, no other force acts on the ship. As the engine exerts a constant force of 4.00 × 10*5 N, the ship moves a distance of 2.50 × 10*6 m in the direction of...
