When jumping, a flea accelerates at an astounding 1000 m/s2, but over only the very short distance of 0.50 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?

The flea will move high to a height of 0.05 meters.

Explanation:

Given that,

Acceleration of the flea,

Distance, d = 0.5 mm = 0.0005 m

Let u and v are the initial and final velocity of the flea. Using equation of motion as :

..........(1)

Using conservation of energy, we get :

h = 0.05 meters

So, the flea will move high to a height of 0.05 meters. Hence, this is the required solution.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
