If a rocket initially at rest accelerates at a rate of 50 m/s² for one minute, its speed will be A)50 m/s. B)500 m/s. C)3000 m/s. D)3600 m/s.

Using the formula:
v = u + at
where, 
u = initial velocity = 0 m/s (since the rocket is initially at rest)
a = acceleration = 50 m/s^2
t = time taken = 1 minute = 60 seconds

Substituting the values, we get:
v = 0 + 50 x 60
v = 3000 m/s

Therefore, the speed of the rocket after one minute of acceleration is 3000 m/s, which is option C.
