A block slides down an inclined plane starting from rest, Ask an Expert

Academics

A block slides down an inclined plane, starting from rest and being pushed with a constant acceleration of 4.60 m/s2 over a distance of 19.4 cm. It then decelerates at a constant rate of 1.06 m/s2 (because of friction), until it again comes to rest. Find the total time the block is in motion.
