u = 12
Answer:
Grace
Step-by-step explanation:
We have to look at the bottom 2 angles, the bigger the angle the wider it is. For Hector, his R angle is 50 degrees and it's 14 wide, but his R angle is 60 degrees, bigger than 50 degrees, and yet the it's only 12.5 wide which is smaller than 14. Grace got it right, 60 degrees is bigger than 50 so it's only natural for it to be wider too.
The software rendering this question really butchered it... I think it's saying the displacement vector for the particle is
Differentiate twice with respect to time 
to get the velocity and acceleration vectors, respectively:
Then at 
, the acceleration of the particle is
which most closely resembles the first choice.
