A child whose weight is 284 N swings out over s pool of water usinga rope attached to the branch of a tree at the edge of the pool. The branch is 11.7 m above ground level and the surface of the poolis 1.48 m below ground level. The child holds onto the rope at apoint 5 m from the branch and moves back until the angle betweenthe rope and the vertical is 26o. When the rope is inthe vertical position, the child lets go and drops into the pool. Find the speed of the child at the surface of the pool?
