A9.08 m ladder with a mass of 23.8 kg lies flat on the ground. a painter grabs the top end of the ladder and pulls straight upward with a force of 260 n. at the instant the top of the ladder leaves the ground, the ladder experiences an angular acceleration of 1.78 rad/s2 about an axis passing through the bottom end of the ladder. the ladder's center of gravity lies halfway between the top and bottom ends. (a) what is the net torque acting on the ladder? (b) what is the ladder's moment of inertia?

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 = ?
