In a classic experiment, a ball (Ball 1) is dropped from a specific height. At the same
time, an identical ball (Ball 2) is launched horizontally from the same height. Which
ball hits the ground first?
A.) The dropped ball (Ball 1) because its path is shorter,
B.) The launched ball(Ball 2) because the ball's velocity is greater.
C.) The two balls will reach the ground at the same time because the horizontal and vertical planes of motion are independent of each other and they were also released from the same height.
D.) It is not possible to determine which ball hits the ground first because of the complex nature of motion

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.
