7. A 5.00 Kg block has a coefficient of friction of .150 on a flat surface. What is its acceleration if you exert a force of 21.0 N sideways on it when it is at rest? (Find the friction force first)2.73 m/s 8. A 10. Kg block is at rest on a level surface. It accelerates from rest to +51.2 m/s in 8.0 seconds when you exert a force of +115 N on it sideways. What is the acceleration of the block? What is the force of friction between the surface and the block, and what is the coefficient of friction? 6.4 m/s, 51 N, 0.52
