I’ve got a couple trigonometry questions that I really need help on. I don’t understand them at all.
5. the work done by a force is given by the expression W=Fd cos theta, where F is the magnitude of the force, d is the distance traveled, and theta is the angle of the applied force to the direction of motion. Calculate the amount of work down by a 5 an force acting at a 75 -degree angle to move a box 30 m
(answer choices shows below)
