An object starts from rest at a height of 7.5 m and slides down to the bottom of a hill. determine how fast the object is going at the bottom of the hill. assume no thermal energy is generated and express your answer using appropriate mks units. round your answer to the nearest thousandth. part b now assume that the object is a hollow sphere and instead of sliding down the hill, it rolls down the hill. it still starts from rest at a height of 7.5 m. determine how fast it will be going at the bottom of the hill. assume no thermal energy is generated and express your answer using appropriate mks units. round your answer to the nearest thousandth object moment of inertia formula hollow cylinder 1mr2 solid cylinder 1 2 mr2 hollow sphere 2 3 mr2 solid sphere 2 5 mr2

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
