a) On the Acme W&W company production line, parts have to be transported 100 m by conveyor belt to a machine area. The parts move at a constant speed of 2.5 m/s. How much time does it take to move a part 100 m?

On the same conveyor belt as described in problem a), the part must slow down to 0.2 m/s over a distance of 0.9 m once it reaches the machine area. The original speed was 2.5 m/s. What is the average acceleration while slowing down? How much time does it take to slow down?

Show steps please!

Thank you!
