The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 59 km/s . To the crew's great surprise, a Klingon ship is 110 km directly ahead, traveling in the same direction at a mere 21 km/s . Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 2.9 s . The Enterprise's computers react instantly to brake the ship. V Part A What magnitude acceleration does the Enterprise need to just barely avoid a collision with the Klingon ship? Assume the acceleration is constant. Hint. Draw a positionversustime graph showing the motions of both the Enterprise and the Klingon ship. Let $0 = 0km be the location of the Enterprise as it returns from warp drive. How do you show graphically the situation in which the collision is "barely avoided"? Once you decide what it looks like graphically, express that situation mathematically. Express your answer with the appropriate units. Mues't
