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.

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.

the kind of relationship between atmospheric  density and altitude is inverse relationship. this means a surge in either will cut the other factor. density is mass per unit volume, it is hard to compute with only altitude 1,291 kilometers given. also, we could also use temperature and pressure to resolve density but they are not delivered.
