Question

A

Express your answer to two significant figures and include the appropriate units.

To the crew's great surprise, a Klingon ship is 120km {rm{ km}} 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 to two significant figures and include the appropriate units. 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 position-versus-time graph showing the motions of both the Enterprise and the Klingon ship. Let x 0 km/s . Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 3.5s km directly ahead, traveling in the same direction at a mere 22km/s

Explanation / Answer

distnace formulas can be used

distance travel by the ship in the time of overtake should be greater than the distance travel by enterprise in the same time.

so we can calculate acceleration

s=ut+at2/2
