A sphere of radius 50 mm and mass 1 kg falling vertically through air density 1.2 kg m attains a steady velocity of 11.0 m sr', If the above equation is applied to its fall, what is the value of k in this case?

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

True or false graphs must include scales that increase by the same amount

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 = ?
