18 A block slides down an inclined plane, starting from rest and being pushed with a constant acceleration of 5.00 m/s2 over a distance of 20.0 cm. It then deceler- ates at a constant rate of 1.00 m/s² (because of fric- tion), until it again comes to rest. Find the total time the block is in motion.
