Answer
$v_{max}=2.25m/s$
Work Step by Step
Remember that velocity and acceleration are related using $$v(t)=\int a(t) dt$$ Since the area under the curve can be expressed as a triangle with base $\Delta t=0.050s$ and $a=90.m/s^2$, the area of a triangle is $$A=\frac{1}{2}bh$$ Substituting known values of $a=90.m/s^2$ and $\Delta t=0.050s$ yields a velocity of $$v=A=\frac{1}{2}(0.050s)(90.m/s^2)=2.25m/s$$
