There are few equations that link acceleration and velocity.
One of them is derived from the definition of acceleration - is the rate of change of velocity in respect with time
a = v-u/t
at=v-u
a = acceleration
v=velocity at the end
u=velocity at the start
t=time
Now put everything you know and solve for time.
6t = 42 -0
6t = 42
t = 42 / 6
t = 7 second
It takes 7 seconds for the roccet to reach a velocity of 42 m/s

Answer:
9.82 rads/sec
Explanation:
We are given;
Time taken; t = 1.6 secs
Number of somersaults = 2
Now, we know that,
1 revolution = 2π radians
And number of somersaults is the same thing as number of revolutions
So,
Total radians = 2π × 2 = 5π
Angular velocity = total number of revolutions/time period = 5π/1.6 = 9.82 rads/sec
Put it in a jug or empty water bottle then when or if it gets full bring it to your nearest hospital or doctors office and ask them to properly dispose of them
Period is seconds/cycle. So just divide number of seconds by the cycles completed. Hope this helps!
