A rocket leaves its platform with acceleration ⃗ a= ( 4.00 ^i+2.00 ^j ) m/s2 and initial velocity v0= ( 8.00 ^i+12.0 ^j ) m/s for 5.00 seconds. After this 5.00 second interval, the rocket’s engines are turned off, and the rocket then travels as a projectile. a. Determine how long the rocket is in the air. b. What is the rocket’s velocity vector (in unit-vector notation) just before it hits the ground?
