find the work done when a 25 kg weight

Work Calculator How could this calculator be better? Soup Calculator Use This calculator will find the missing variable in the physics equation for Work, when two of the variables are known. Work Equation for these Calculations W = F s Where: W = Work F = Force s = displacement
A weight lifter lifts a 390-N set of weights from ground level to a position over his head, a vertical distance of 1.95 m. How much work does the weight lifter do, assuming he moves the weights at a constant speed? A load of mass 80 kg fell down from the floor of a lorry which is 1.2 m high. Calculate work done by gravity on the land.
So work done equals final kinetic energy minus the initial kinetic energy. And this equation can be derived from here. And the equation is basically saying that the work done on a body basically tells how much kinetic energy is added to the body. So in this example, if we find out that 10,000 joules of kinetic energy was added to this body
In physics, work is the energy transferred to or from an object via the application of force along a displacement.In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled. A force is said to do positive work if when applied it has a component in the direction of the displacement of the point of
Nov 24, 2016. Ramp Work Work done. In summary, a man weighing 85 kg pushes a crate 4.00 m up a ramp at a 20 degree angle to the horizontal with a force of 500N, resulting in a negative magnitude. To determine the work done, the x and y components of the forces acting on the man are set up and the force applied is found to be parallel to the ramp.
A 50 k g man with 20 k g load on his head climbs up 20 steps of 0.25 m height each. The minimum work done by the man on the block during climbing is The minimum work done by the man on the block during climbing is

Calculate the work done. Solution: Use WD = F x d d = 0 because the boulder does not move = 2000 x 0 so WD = 0 If an object does not move when the force is applied then no work is done. Work is only done if the object moves. Gravitational Potential Energy Whenever we lift up an object we are providing a force to act against gravity.
Mass of man = 70 kg . Weight carried = 10 kg . Height above ground h = 100 m . Work done =??? Total mass at top of tower = 70 + 10 . M = 80 kg . For a body of mass m to raise to height h above earth, Work done = potential energy stored = M × g × h . Let g = 10 ms-2 . So, work done will be = 80×10×100 = 80,000 J = 80 KJ
15. A .50-kg object moves in a horizontal circular track with a radius of 2.5 m. An external force of 3.0 N, always tangent to the track, causes the object to speed up as it goes around. The work done by the external force as the mass makes one revolution is: A) 7.5 J B) 24 J C) 47 J D) 94 J E) 120 J
Work is done when an object moves in the same direction as the force is applied and also when force remains constant. This online Work Calculator helps you find out the work, force or distance based on the other two parameters. Work, force and distance are related to each other.

3. If an object is being pushed across a horizontal surface, the equation for the work done is W = Fs W = F s, where s s is the horizontal displacement. If an object is being lifted to a height of h h, the equation for the work done is W = Fh W = F h, where h h is the vertical displacement. If an object is being pushed up a slope, or if a human
