Asmall block of mass m = 200 g is released from rest at point ⓐalong the horizontal diameter on the inside of a frictionless, hemispherical bowl of radius r = 30.0 cm (fig. p8.41). calculate (a) the gravitational potential energy of the block-earth system when the block is at point ⓐ relative to point ⓑ, (b) the kinetic energy of the block at point ⓑ, (c) its speed at point ⓑ, and (d) its kinetic energy and the potential energy when the block is at point ⓒ.

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

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
