The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 51 km/skm/s . To the crew's great surprise, a Klingon ship is 140 kmkm directly ahead, traveling in the same direction at a mere 30 km/skm/s . Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 6.7 ss . 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.
