A68.2 kg base runner begins his slide into second base while moving at a speed of 4.33 m/s. he slides so that his speed is zero just as he reaches the base. the acceleration of gravity is 9.8 m/s 2 . what is the magnitude of the mechanical energy lost due to friction acting on the runner?

Explanation:

We know that:

where is the initial energy, is the final energy and is the energy lost due to friction.

so:

Where M is the mass and V is the velocity of the runner, so:

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

answer: decibel

explanation:
