Can you solve this problem.

The velocity of a projectile as a function of the time t is given as follows: D(t) = (78t + 80)i + (78t + 49)j + (50t + 100)k. It is also known that the initial position of the projectile at t = 0 is 7(0) = (0, 0, 13) Find the position vector of the projectile as a function of time t is " (t)
