An 82-kg fireman slides 5.2 m down a fire pole. He holds the pole, which exerts a 550-N steady resistive force on the fireman. At the bottom, he slows to a stop in 0.45 m by bending his knees.
Determine the acceleration of the fireman while stopping. Express your answer with the appropriate units. Enter a positive value if the acceleration is downward and negative value if the acceleration is upward.

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 = ?
