The muscles in arm 1 shown below are composed of 80% slow twitch and 20% fast twitch fibers. The muscles in arm 2 are composed of 20% slow twitch and 80% fast twitch fibers. Which arm would be able to perform the most repetitions with the 5 kg-dumbbell, and why?

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
