A single force acts on a particle-like object of mass m kg in such a way that the position of the object as a function of time is given by x = 3t - 4t2 + t3, with x in meters and t in seconds.

Given the time of flight for a projectile fired horizontally was o. 66 seconds, and it landed 3:3 m from where it was launched, the projectile's muzzle velocity was: (A) 0.20 m/s, (B) 0.22 m/s, (C) 0.50 m/s, (D) 5.0 m/s, (E) none of the above.
