A crate weighs 820N and rests on a 34degree incline. You can keep it from sliding down the incline by pushing on it with a force of 240N applied parallel to the incline.

1)Calculate the coefficient of static friction between the crate and the incline.

2)What is the greatest force you can apply before the crate begins to move up the incline.
