Work equals force times distance and kinetic energy equals one-half the mass of the object times its velocity squared, so: W = F d = 1 2 m v 2. W=Fd=\frac {1} {2}mv^2 W = F d = 21. . mv2. Substitute the measurements for force, distance and mass into the equation. 3. A train covers a distance of 20 km and that the force causing it to accelerate is 0.5 m/s┬ . Calculate the work done? Given that, Displacement d = 20 km. Force f = 0.5 m/s┬ Work w = f * d. w = 20 * 0.5. Work done is 10 J. 4. How to find the work done by an object using the velocity chnage and mass? According to newton's second law F = ma The work done on an object is calculated by multiplying the force applied to the object by the distance over which the force is applied. In this case, the force applied is 100 N and the distance is the height of the ramp, which is 3.0 m. Therefore, the work done on the box is 100 N * 3.0 m = 300 J. Physics questions and answers. Work, Power and Energy Worksheet Work and Power 1. Calculate the work done by a 47 N force pushing a pencil 0.26 m 2. Calculate the work done by a 47 N force pushing a 0.025 kg pencil 0.25 m against a force of 23 N. 3. Calculate the work done by a 2.4 N force pushing a 400. g sandwich across a table 0.75 m wide 4. A weightlifter lifts a weight of mass 25.0 kg through a distance of 0.610 m, then lowers it gently. He does this 25 times. Calculate the net work done by the force of friction due to the rope rubbing ; A person lifts a 4.3 kg centimeter block a vertical distance of 1.10 m and then carries the block horizontally a distance of 10.0 m. Calculate: i the work done by the man, and ii the increase in his potential energy. g=9.8 m s 2. Login. A man of mass 50 kg climbs up a ladder of height 10 m. Calculate: 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. Calculus questions and answers. 1. Use correct units! a) Calculate the amount of work done if a 418 lb. rat is lifted 10 feet off the ground. b) Convert weight to kilograms, distance to meters. (hundredths) c) Calculate work done, metric version. I foot = 0.305 meters 2.2 pounds = 1 kg (nearest unit) i) 418 lbs. = kg ii) 10 ft. = meters 2. I need help solving this! The work, W (in joules), done when lifting an object varies jointly with the product of the mass, m (in kilograms), of the object and the height, h (in meters), that the object is lifted. The work done when a 120-kilogram object is lifted 1.8 meters above the ground is 2116.8 joules. How much work is done when lifting Solution: Step 1: Write down the values. F = 20 N d = 500 m Step 2: Use the work done formula and place the values. W = F×d 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.
