Question

Find the work done if a force of 1000 N is applied on a load and it moves a distance of 50 cm .​

Answer 1

Answer:

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

Explanation:

Friction does negative work. Example 10: In Example 9, the work done by force of friction is -112,000J. Use the work formula to calculate the force applied by friction if brakes were used within a distance of 56m. Solution: Using Work formula: W = Fk x ; -112,000J = Fk(56m); Fk =-2000N.

Answer 2

Answer:

500 joules

Explanation:

Work done = Force × Displacement

Work done = 1000 × 0.5

Work done = 500 joules
