Two projectile are thrown at the same ti...

Two projectile are thrown at the same time from two different points. One projectile thrown from the origin has initial velocity `3hati+3hatj` with respect to earth. The other projectile has initial velocity `ahati+bhatj` with respect to earth thrown from the point `(10,5)`.
(`hati` is a unit vector along horizontal `hatj` along vertical).If the projectile collides after two seconds, then choose from following the correct options(s). All values are in SI units.
