A force of 20 N acts on a body at an angle of 60 degrees to its direction of motion. If the body moves 5 m, what is the work done?
Q1. A force of 20 N acts on a body at an angle of 60 degrees to its direction of motion. If the body moves 5 m, what is the work done?
Answer: 50 J
Explanation: Work done = F * d * cos(θ) = 20 N * 5 m * cos(60°) = 20 * 5 * 0.5 = 50 J.
