Once the refrigerator was loaded, Stick Man left to deliver it. It took 45 seconds to accelerate from rest to its top speed of 11 m/s (25 mph) in the residential neighborhood. At what rate did the truck accelerate?

You will need your equation sheet (Links to an external site.) for this question!

Group of answer choices

495 m/s2

0.244 m/s2

1.8 m/s2

4.09 m/s2

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.
