A 24 kg child descends a 5.0 m high slide and reaches the ground with a speed of 2.8 m/s.   a.     How much  energy was dissipated due to friction in the process?

When a book falls from a shelf to the ground without anyone pushing on it, no work is done on the book. true or false

The energy produced as a result of this flow of electrons from atom to atom is called

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 = ?
