Ahardworking ant must supply 0.00805 n to pull a small piece of fruit at constant velocity over a distance of 9.80 cm up a small hill to the entrance of the colony. if the coefficient of kinetic friction between the piece of fruit and the 15.8â° sloped hill is 0.400, calculate the work done by the ant by pulling the piece of fruit up the hill.

In physics, the definition of work is simply the product of force exerted and the displacement. Therefore in this case, work done by the ant is:

Work = 0.00805 N * 9.80 cm * (1 m / 100 cm)

Work = 7.889 x 10^-4 J

newton's first law of motion

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.
