In the figure, a baseball is hit at a height h = 1.10 m and then caught at the same height. It travels alongside a wall, moving up past the top of the wall 1.3 s after it is hit and then down past the top of the wall 3.4 s later, at distance D = 55 m farther along the wall. (a) What horizontal distance is traveled by the ball from hit to catch? What are the (b) magnitude...

A model rocket is fired straight up from the top of a 55-m-tall building. The rocket has only enough fuel to burn for 3.0 s. But while the rocket engine is burning fuel, it produces an upward acceleration of 60 m/s2. After the fuel supply is exhausted, the rocket is in free fall and just misses the edge of the building as it falls back to the ground. Ignoring air resistance, calculate 1. Determine the height above the ground of...
