A golfer on a level fairway hits a ball at an angle of 28° to the horizontal that travels 109 yd before striking the ground. He then hits another ball from the same spot with the same speed, but at a different angle. This ball also travels 109 yd. At what angle was the second ball hit? (Neglect air resistance.)

What is work? how much work is done to move an object 0 meters?

Which situation will have the highest resistance? a. long wire and high temperatureb. short wire and high temperaturec. long wire and cold temperaturedshort wire and low temperature

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
