Question

formula for work done by friction​

Answer 1

Answer:

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.
