Finding velocity with given force

2. F=ma, a=F/m, V^2 = Vinitial^2 + 2a(x_final - x_inital)



3. I got an acceleration at .84 by doing a=.2/1.7, which came out to be .117647 m/s^2, which I plugged into the v equation for √.44^2+.2*.117647+.57 which gave me an answer of .572 m/s. I haven't plugged it in yet because I lose points if it is wrong so I just wanted to verify my work here.

And then I wasn't sure how to do the second one

I did put in that .572 and that was the wrong answer so I'm not sure if I had the wrong equation or just did incorrect calculations.
