Question 14

A drone D D\,D moves with constant acceleration. At time t=0t = 0t=0, D D\,D is moving in the direction (5i+12j)(5\mathbf{i} + 12\mathbf{j})(5i+12j) with speed 26 ms-1. 4 seconds later D D\,D is moving with velocity (14i+30j) ms−1(14\mathbf{i} + 30\mathbf{j}) \text{ ms}^{-1}(14i+30j) ms−1.

Find the acceleration of DDD.
