A car accelerates from rest to a velocity of 8 meters/second in 6 seconds. What is its average acceleration over this period of time?

1.33 m/s²

Explanation:

u = 0 ( starts from rest )

v = 8 m/s

t = 6 s

a = v - u / t

8 - 0/6

= 1.33 m/s²

Hope this helped...

i think they are all correct

explanation:

they seem good

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.
