An axe used to split wood is driven into a piece of wood a distance of 3.0 cm. if mechanical advantage of the axe is 0.85. how far apart is the wood split?

3.53 cm

Mechanical advantage = Input distance/output distance

Input distance = 3.0 cm

Mechanical advantage = 0.85

Output distance = Input distance/Mechanical advantage

                           =  3.0/0.85

                           = 3.53 cm

it has to be b, about 97 percent.

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.
