A car starts from rest and reaches a speed of 20m/s in 5 second what is the acceleration of the car

4m/s^2

Explanation:

a=v‒u/t (here v is final velocity &u is initial velocity)

a=20m/s‒0m/s/5s

a=20m/s/5s

a=4m/s^2

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.
