When jumping, a flea reaches a takeoff speed of 1.2 m/s over a distance of 0.46mm. With answers use two significant figures.
A) What is the flea's acceleration during the jump phase?
B) How long does the acceleration phase last?
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.)
