(a) A force of 50 N inclined at an angle of 300 with the vertical axis moves a square block of mass 6 kg that is initially at rest on a horizontal table. The force is applied with an inextensible rope attached at the top right corner of the block. Find the velocity of the block after 8 secs. Take coefficient of kinetic friction as 0.2.
Two blocks A and B with masses mA = 10 kg and mB = 4 kg are connected by an inextensible cable and released from rest shown in Figure 1 (where block A is placed in position C). The cocfficients of kinetic friction between two blocks and the 30° inclined plane are uA = 0.1 and MB = 0.3. The cable is in tension in the entire motion and the sizes of blocks are negligible.

To apply Newton’s second law and the theorem of conservation of energy to solve kinetic problems. A bungee jumper wants to jump off the edge of a bridge that spans a river below. The jumper has a mass m, and the surface of the bridge is a height h above the water. The bungee cord, which has lengthL when unstretched, will first straighten and then stretch as the jumper falls.Assume the following: The bungee cord behaves as an ideal spring once it begins to stretch and has spring constant k. The jumper does not actually jump but simply steps off the edge of the bridge and falls straight downward. The jumper's height is negligible compared to the length of the bungee cord. Thus, the jumper can be treated as a point particle. Use g for the magnitude of the acceleration due to gravity. How far below the bridge, d, will the jumper eventually be hanging, once the jumper stops oscillating and comes finally to rest? Assume that the jumper does not touch the water. Express your answer in…
