On a ride known as the graviton a rider leans against a wall (vertical) inside a cylinder (think about being on the inside wall of a tin can. The ride spins up around its center axis to its maximum speed (where it stays) and the floor drops away. The rider does not fall down due to static friction. Draw fbd for the rider. (not graded) Write out the force equations for vertical forces (up/down from surface of earth) when the rider is not touching the floor but is touching the wall. How many vertical forces are on the rider?

Give an example in which the electrical energy changes to light energy

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
