Velocity is nothing but dr/dt i.e. slope. So you have used polyfit and you got the slope already.

You have done with 2a and 2c.
2b. Since you have computed the polynomial coefficients in the p vector, then p(1) tells you the velocity (slope), and p(2) gives the initial range (intercept). Natural, this means 
and 
in the slope-intercept form, 
.
and in the slope-intercept form, .3. This part requires you to solve 
for time t when 
. I believe that you can solve this algebraic equation easily.
