Einstein and lorentz, being avid tennis players, play a fast-paced game on a court where they stand 19.0 m from each other. being very skilled players, they play without a net. the tennis ball has mass 0.0580 kg. you can ignore gravity and assume that the ball travels parallel to the ground as it travels between the two players. unless otherwise specified, all measurements are made by the two men.

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 β β n (9.8)(45β3 xi) i = 1 Ξ΄x express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
