In a car lift used in a service station, compressed air exerts a force on a small piston of circular cross-section having a radius of 3.92 cm. this pressure is transmitted by a liquid to a second piston of radius 15.6 cm. what force must the compressed air exert in order to lift a car weighing 14600 n? answer in units of n.

What is the speed of an object at a given moment?

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
