Multiple Choice
Multiple ChoiceA survey drone has just completed a scan at x,y coordinates (57m, 8m) at t=0. It needs to return to a lab located at (-115, 72) m. If its initial velocity is 16m/s in the +y-direction, and it has only 18s of battery life remaining, what constant acceleration (magnitude and direction) does it need to reach the lab?
A
2.8 m/s2; along –x axis
B
1.8 m/s2; 51.8° below –x axis
C
2.8 m/s2; above –x axis
D
1.3 m/s2; 24° above –x axis
