## anonymous one year ago A car starts at rest and accelerates at a rate of 2.75 m/s/s. What is its speed 3.726 seconds after it starts to move?

1. anonymous

$a=\frac{v_f-v_i}{t}$ $2.75~ m/s^2=\frac{v_f-0}{3.726~s}$

2. anonymous

So the answer would be .738 m/s?

So I need to multiple 2.75 by 3.726?

5. anonymous

yes multiply and then it's 10.2 m/s
