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?
b) 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?
c) When leaving the machine area described in problems a and b, the part reverses direction and starts with a velocity of 0.2 m/s. It is accelerated at 1.5 m/s^2 for its journey back a distance of 5m. How long does it take the part to travel the 5m distance? What is the final velocity of the part?
Show steps please!
Thank you!
