Ryan holds a ball still at position A and then releases it. His friend stops the ball at position F. The image shows the path of the ball from position A to position F. Identify the kind of energy the ball has at each position.

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.

The momentum of a man riding his bicycle downhill can be calculated. the bicycle and the man have a combined mass of 40 kg. the velocity of the bicycle is 10 m/s. calculate the momentum.
