v = at
plug in your numbers. watch the units.
A rocket initially at rest accelerates at a rate of 80 m/s^2 for 0.74 min.
What is its speed at the end of this time? Answer in units of m/s.
Plz help and explain

but arent you supposed to look for the speed?
yes -- velocity = speed. Look at the units:
(m/s^2)*(s) = (m/s)
acceleration is how much the speed changes each second: (m/s)/s = m/s^2
so, in your example, the speed grows by 80m/s every second.
quantity = rate * time, such as
5 pages/day * 2 days = 10 pages
etc.
