A cart with a mass of 8.0 kilograms is attached to a spring. When
released from the spring, the cart travels up a hill with a height of 11
meters. The cart comes to rest at the top of the hill. The spring is 100%
efficient. How much elastic potential energy was required to bring the
cart to rest at the top of the hill? Include your units.

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio Ο1/Ο2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
