In an isolated system, a red ball of mass m moves to the right with speed v. It strikes a green ball, of mass 2m, which was initially stationary. After the collision, the red ball remains stationary. How does
the green ball move?

A. To the left, with speed v/2

B. To the right with speed 2v

C. To the right, with speed v/2

D. To the left with speed 2v

electromagnetic waves travel through space with vacuums. give me brainliest if right.

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.
