Answer:
Group B is farther from the airport.
Step-by-step explanation:
To find the distance of each group to the airport we can use the law of cosines in the triangle created with the two movements done and the resulting total distance.
Law of cosines:
For group A, we have the sides of 200 miles and 75 miles, and the angle between the sides is (180-68) = 112°, so the third side of the triangle is:
For group B, we also have the sides of 200 miles and 75 miles, and the angle between the sides is (180-51) = 129°, so the third side of the triangle is:
The distance from group B to the airport is bigger, so group B is farther from the airport.

See below
Step-by-step explanation:
See the attached image. My calculation seems a bit off from what I expected, but the reasoning might help.
The paper is trailing the dropped object and a mark is made every 0.020 seconds. By measuring the difference between the dots and dividing by the time, we can calculate the average speed at the the final 2 locations. The difference in these speeds is due to acceleration, as shown in the calculation.
My result wasn't what is considered correct for Earth's acceleration of gravity, but I offer possible explanations. Please check my calculations.
