A car has a mass of 2000 kg and has 900 kJ of kinetic energy from its motion. What is the velocity of the vehicle?

the average speed is 24.57 km/hr

scientific laws are the result of testing theories and proving them to be facts.

c. newton's third 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.
