If a single constant force acts on an object that moves on a straight line, the object's velocity is a linear function of time. the equation v = v_i + at gives its velocity v as a function of time, where a is its constant acceleration. what if velocity is instead a linear function of position? assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = v_i - kx, where k is a constant coefficient and x is the position of the object. find the law describing the total force acting on this object. (enter an expression for the magnitude of the total force. use the following as necessary: m, k, and v.)

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
