Dwayne Douglas Johnson, also known by his ring name the Rock, is an American-Canadian actor, producer, businessman, retired professional wrestler, and former American football and Canadian football player. He wrestled for the World Wrestling Federation for eight years prior to pursuing an acting career. As a form of intensive exercise for the preparation of his new movie he wishes to pull the box shown below to 3m above the ground. In order to do that he exerted a constant vertical force F =200N. Determine the final velocity of the block when it has risen 3m above the ground starting from rest. Assume that the block has a mass of 20kg. The final velocity of the block is | m/s. F 0.25m

Can you draw a free body diagram on this problem and solution? so I can clearly understand. An open tank in the shape of a frustum of a cone is bound by two hoops, one at the top and the other at the bottom. The diameters at the top and bottom are 2m and 3m, respectively. If the total bursting force is to be taken care of by the hoops, find tension in each hoop if water stands 2 m in the tank. Height of tank is 3.0 m.
