A ball was dropped from rest from level “A” (12 m above the liquid surface, level “B”). Through the liquid,
the ball was applied by deceleration of 120t4 m/s?,
where t is the time in seconds, the ball stopped at level
"C". Calculate:
a) The velocity of the ball at "B"
b) The time taken by the ball from "B" to "C"
C) The distance between "B" and "C"​

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.
