I might be wrong but it should be 1
We are given the distance as a function of time:
s = 4.9 t^2 + 350
To get the velocity, we take the first derivative and
substitute the value of t = 2:
ds = 9.8 t dt
ds / dt = 9.8 t
velocity = 9.8 (2)
<span>velocity = 19.6 m/s</span>
1/11 is your answer
Hope this helps :)
