4. A projectile is launched from ground level at an angle of 45 degrees. It hits a target that is 2000 feet away and at ground level. What was the initial speed (Vo)? Take g= 32 and neglect air resistance. Treat numbers (including g) as exact and either give the exact answer or a decimal approximation accurate to three places to the right of the decimal.
