Utilize integral formulations to solve the following: a block of wood is projected up an inclined plane with initial speed V0. If the inclination angle theta is 30 degrees and the coefficient of sliding friction mu=.1, in terms of v0, a) discover the total time for the block to return to the point of projection and b) find the total distance the block travels through that time. Important note: the final velocity at the projection point is not the same as the initial velocity at the projection point due to the influence of friction.
