Which situation describes work being done according to the work-kinetic energy theorem? A. A girl riding her bicycle on the road going 10 m/s B. A parent holding a sleeping baby with one arm C. A boy pushing a box across the floor at a velocity of 4 m/s D. A driver pressing his car breaks in order to come to a stop

the answer is kevlar

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.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
