A block with a mass of 2.45kg is pushed up an incline plane that makes an angle of 34.2o with respect to the horizon. The block-surface interface has a coefficient of friction of 0.315.

(a) How much work is necessary to push the block up the incline to a height of 2.58m?

(b) How much work did the frictional force do on the block (hint: be aware of the direction of the force of friction)?
