A racquetball is initially at a height of 5feet above a solid marble floor. The ball is traveling 6m/sec at an angle of 40degrees below the horizontal. Determine the minimum distancealong the floor from the point of initial impactwhere the ball will no longer bounce above a height of 7incheson earth and on mars.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
