oh. I forgot about that. Disregard my answer. Look at Damon's answer.

1 correct 2 I think you are missing an x somewhere in the equation.

This is from one of your previous answers. You can do it with work if you wish or you can do it with F = m a with work work done = Force in direction of motion * distance Force in direction of motion = F cos 38 = .788 F work done = .788 F * 3.4 meters = 2...
