http://www.brainmass.com/homeworkhelp/physics/developmentconsumptionofenergy.php

Extractions: Topic: Development and Consumption of Energy change topic change subject Determining final velocity using initial velocity and displacements in a ramp question. A 5 kg bowling ball is rolled back to the bowler over a ramp system. If the ball is given an initial velocity of 0.6 m/s at its starting pointÂ’s height which is 100 cm, what is the balls velocity at its ending point at 40 cm, after going over a height of 45cm first? So the ball leaves the first position goes through a dip up to 45 cm and ends at 40 cm. Download a solution to this problem.

Extractions: Q - Angle between F and S Work will be zero if F or S = or angle Q = 90 o In the current situation the wall is not moving and S is therefore zero. It follows that Work is zero, that is no work is done. A 0.2 kg rubber ball is dropped from the window of a building. It strikes the sidewalk below at 30 m/s and rebounds at 20 m/s. Find the change in momentum of the ball as a result of the collision with the side walk (in kg m/s). Mass of the rubber ball = 0.2 kg = m Initial velocity = 30 m/s = v Final velocity after collision = -20m/s = v Change in momentum = mv - mv = m(v - v = 10 kg m /s Q. A 2.0 kg block is thrown upward from a point 20m above Earth's surface. At what height above Earth's surface will the gravitational potential energy of the Earth block system have increased by 500J?

A120 lb person is being lifted aloft by a rocket which accelerates uniformly to an upward speed of 300 ft/sec in 2 sec. a) What is the upward acceleration in multiples of g? Mass of the man = 120lb Final speed of the rocket = 300 ft/sec Time = 2 sec Acceleration of the rocket can be calculated from first equation of motion v = u + at 300 = + a x 2 a = 150 ft/sec b) What is the apparent weight of the person during acceleration? Free body diagram: N - Normal reaction which is equal to the apparent weight of the man. mg - Actual weight of the man ma = N - mg N = ma + mg = m (a + g) = m (4.7g + g) = 5.7mg = 5.7 x 120 g = 684g = 684 lbf. Q. A short 10 gram string is used to pull a 50 gram toy across a frictionless horizontal surface. If a 3.0 x 10 Newton force is applied horizontally to the free end. Find the force of the string on the toy, at the other end. Mass of the string = 10 grams = 10 kg Mass of the toy = 50 gm = 5 x 10 kg Mass of toy + string = 10 + 5 x 10 = 6 x 10 kg Force applied F = 3.0 x 10 N
