Two crates, one with mass 5.4 kg and the other with mass 8.2 kg, connected by a light rope. the coefficient of kinetic friction between each crate and the surface is 0.43.the crates are pulled to the right at a constant velocity of 2.9 cm/s by a horizontal force. determine the ratio of the magnitude of the applied horizontal force to the magnitude of the tension in the rope connecting the blocks. use 9.80 meters per second squared for acceleration due to gravity.

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?

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 = ?
