Which car would be the most economic over its 12 year lifetime?
Use data from the table above to support your answer.
You should include the difference in cost in your answer.

tube or goog will be great resources to find the answer to the question that you're asking

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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.
