  1. A force F is applied to a block (m=5.0kg) at rest with a coefficient of static friction (0.80) on a plane incline 30 degrees. • a. • What force F must be applied to get the block on the verge of moving? • b. • Using this force, the block begins to move down the ramp (coefficient of kinetic friction = 0.40). What acceleration does it have?
