An engineer is considering possible trajectories to use for emergency descent of a lunar module from low moon orbit to the lunar surface and decides it to) to investigate one for which the vertical component of velocity as a function of time is described by vy(t) = voe 2:2 where vo = 0.49 km/s, to = 390 s, and o = 65 s. Part F = to-o= 325 s? Recall that acceleration is For this trajectory, what would the vertical component of acceleration for the module be at time tm the derivative of velocity with respect to time.

4.57 m/s

Explanation:

We are given that

1km=1000 m

Substitute the values

i think the answer is a and b

i wish you luck

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
