Physics
1 answer:
Bad White [126]3 years ago
5 0

Answer:  16 meters per second

<u>Explanation:</u>

 The derivative of the position is the velocity.

 The derivative of the velocity is the acceleration.

                  x(t) = 2t² + t³ + 1

         x'(t) = v(t) = 4t + 3t²

x''(t) = v'(t) = a(t) = 4 + 6t

                  a(2) = 4 + 6(2)

                         = 4 + 12

                         = 16
