Which statement about work and power correctly describes an automobile race? The cars do different amounts of work depending on how fast they finish. The car that finishes last has the lowest power. The car with the greatest power travels the greatest distance. The cars do different amounts of work depending on their power.

There are two correct statements here,

1. The car that finishes last has the lowest power.

2. The car with the greatest power travels the greatest distance.

Explanation:

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.
