The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 51 km/s . To the crew's great surprise, a Klingon ship is 110 km directly ahead, traveling in the same direction at a mere 30 km/s. Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 5.2 s. The Enterprise's computers react instantly to brake the ship. What magnitude acceleration does the enterprise need to just barely avoid a collision with the klingon ship? Assume the acceleration is constant.

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.
