Work and Power

Question 1 • 350CR Integrated Science

A force of 100 N is applied to a crate at an angle of 60° to the horizontal surface. The force causes the crate to move 2 m across the floor. How much work is done on the crate?

Answer
A
50 J
B
100 J
C
200 J

Explanation

Work is the component of the force in the direction of motion multiplied by the distance: W = Fd cos θ. Here, W = 100 N × 2 m × cos 60° = 200 × 0.5 = 100 J, so the correct choice is 100 J.
