Final answer:
The work done by a 60 N force pushing a bicycle pedal through a distance of 2 meters is calculated using the formula Work = Force × Distance, resulting in 120 J. The correct answer is (a) 120 J.
Step-by-step explanation:
The work done by a 60 N force pushing a bicycle pedal through a distance of 2 meters is calculated using the formula Work = Force × Distance, resulting in 120 J. The correct answer is (a) 120 J.
The question asks for the work done by a force applied to a bicycle pedal. Work can be calculated using the formula Work = Force × Distance × cos(θ), where θ is the angle between the force and the displacement. In this scenario, since the force applied to the pedal is in the same direction as the displacement, θ is 0 degrees and the cosine term is 1. Therefore, the work done can be simplified to Work = Force × Distance.
Given that a 60 N force is applied through a distance of 2 meters, we can calculate the work using the equation:
Work = 60 N × 2 m = 120 J (joules)
Thus, the correct answer is (a) 120 J.
