The Alaskan Troopers are mounting a rescue mission and are dropping supplies to some stranded hikers. The troopers are flying at 100 m/s and drop their payload
600 m in advance of the target.
19.
How high above the ground were they flying?
a. 60 m
b. 600m
c. 176 m
d. 1800 m

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
