An object, moving with constant acceleration and zero initial velocity of 129 m/s how high will it be after 4.0 s

596m

Explanation:

S = ut + 1/2at^2

u = 129m/s, t = 4s and a = 10m/s^2

S = (129×4) + 1/2(10 × 4^2)

S = 596m

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.
