A 12.0kg box rests on a smooth table. A downward force of 40.0N is applied the box. What is the normal force (FN)?

What is the temperature in degrees celsius of a substance with a tempature of 49k

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

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 = ?
