A1.0 kg object is attached to a string 0.50 m. it is twirled in a horizontal circle above the ground at a speed of 5.0 m/s. a ball is moving on a circular path. the ball is currently at the top right position of the circle. point a is above and to the left of the ball. point b is above and to the right of the ball. point c is down and to the right of the ball. point d is down and to the left of the ball and inside the circle near the center. what is the magnitude of the centripetal force acting on the object? 2.5 n 10. n 25 n 50. n

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 = ?
