n an amusement park ride, a person with mass 52 kg stands against the wall of a cylindrical room with radius 14.3 and coefficient of friction 0.594 between the rider and the wall. The ride begins to rotate. When the ride attains a constant speed of 7.4 m/s, the floor drops down ward. The rider remains pinned against the wall. What is the magnitude of the force that the rider feels pinning him against the wall

Which property of fossils allow scientists to determine the relative rock ages..

Lacie kicks a football from ground level at a velocity of 13.9 m/s and at an angle of 25.0° to the ground. how long will the ball be in the air before it lands? how far will the football travel before it lands?

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
