Question

a 25 newton force applied on an object moves it 50 meters. the angle between the force and displacement is 40.0°. what is the value of work being done on the object? a. 0 joules b. 9.6 × 102 joules c. 1.2 × 103 joules d. -9.6 × 102 joules e. -1.2 × 103 joules

Answer 1

Work = force × distance × cos(angle)

work = (25)(50)(cos (40))

work = 957.56 Joules

= 9.6x10^2 Joules
