10. [-/5 Points] DETAILS MY NOTES Consider a trajectory in space with acceleration vector a(t) = (et, -1, 2t). Solve the initial value problem to find the trajectory r(t) for the problem with initial velocity v(0) = (8, 0, -5) and initial position (0) = (5, 4, -9). (Your instructors prefer angle bracket notation for vectors.) r ( t ) =
