Two billiard balls move in a straight line with the following equations of motion: Xi = -6.0 m + (0.5 m/s) t
X2 = 10.8 m + (-2.5 m/s) t
At what time do the billiard balls collide (at the same final position)?

answer: i don't know the answer good luck

explanation:

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.
