4) Please answer the following questions:

Two children are playing on a 147-m-tall bridge. One child crops a rock (initial velocity zero) at f = 0. The other waits 1.1 s and then throws a rock downward with an initial speed vq. If the two rocks hit the ground at the same time, what is vq? A rock is cropped from a tall bridge into the water below. If the rock begins with a speed of zero and has a speed of 25 m/s just before it hits the water, what is the height of the bridge as measured from the surface of the water? when a large bone such as the femur is broken, the two pieces are often pulled out of alignment by the complicated combination of tension and compression forces that arise from the muscles and tendors In the leg (see the X-ray image in figure A). To realign the bones and allow proper healing, these forces must be compensated for. A method called traction is often employee. If a total tension force of 320 N is applied to the leg as depicted In figure B to realign the parts of the femur, how much mass m must be attached to the bottom pulley? kg
