When jumping, a flea reaches a takeoff speed of 1.5m/sm/s over a distance of 0.70 mm. 

Part A: What is the flea's acceleration during the jump phase? Express your answer in meters per second squared.

Part B: How long does the acceleration phase last? Express your answer in seconds.

Part C: If the flea jumps straight up, how high will it go? (Ignore air resistance for this problem; in reality, air resistance plays a large role, and the flea will not reach this height.) Express your answer in meters.
