A boat turns off its engine while traveling at 10 m/s, and then a constant drag force slows the boat to a stop, while traveling an additional 80 m. The mass of the boat is 600 kg . What is the magnitude of the constant drag force, in Newtons, required to stop the boat in 80 m?

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 = ?
