A baseball leaves the bat with a velocity of 55 m/s. The ballpark fence is 120 m away. Does the ball reach the fence if it leaves the bat traveling upward at an angle of 30º to the horizontal? Also, if you could explain the answer, that would help, because I don't really understand the question. :) thank you!

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
