Aparticle undergoes two displacements. the first has a magnitude of 11 m and makes an angle of 82 ◦ with the positive x axis. the result after the second displacement is 8.7 m directed at an angle of 135◦ to the positive x axis using counterclockwise as the positive angular direction schoenzeit (ms83473) – assignment 01-1 – pusch – (19512020) 5 135◦ 82◦ 11 m 8.7 m find the angle of the second displacement measured counterclockwise from the positive x axis (i. e., a positive angle). answer in units of ◦ .

Discuss how the hardness or softness of the landing surface is related to the time required to stop the egg

(a) if the pressure in gas is doubled while its volume is held constant, by what factor do (i) vrms and (ii) change? (b) is it possible to boil water at room temperature (20oc) without heating it? explain.

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
