When jumping, a flea accelerates at an astounding 1100 m/s2 , but over only the very short distance of 0.58 mm ?

If a flea jumps straight up, and if air resistance is neglected (a rather poor approximation in this situation), how high does the flea go?

Answer;

=0.065 m or 65 mm

Explanation;

v = √(2as)

= √(2 * 1100m/s² * 0.00058 m) = 1.276 m/s

Therefore;  initial velocity = 1.276 m/s

Then s = v² / 2g

g = 9.8 m/s²

            = (1.276m/s)² / 19.6 m/s²

            = 0.065 m  or 65 mm

the answer is to check all of them! they all apply well at least i think so!

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
