A force of 75 cap n at an angle of 15 degrees to the direction of motion moves a chair 3 m Which change would result in more work being done on the chair?

Work is W = Fd cos θ, where θ is the angle between the force and the direction of motion. Decreasing the angle from 15° to 10° increases cos θ, so more of the force acts along the chair’s motion and the work increases. Choice D, decreasing the angle to 10°, results in more work.
