A rocket is fired at an angle from the top of a tower of height h0 = 36.8 m . Because of the design of the engines, its position coordinates are of the form x(t)=A+Bt2 and y(t)=C+Dt3, where A, B, C , and D are constants. Furthermore, the acceleration of the rocket 1.20 s after firing is a⃗ =( 3.30 i^+ 2.50 j^)m/s2. Take the origin of coordinates to be at the base of the tower.

What are the x- and y-components of the rocket's velocity 12.2 s after it is fired?
