I think its b too but i may be wrong

Centripetal force is give by F = mv^2/r
Since
F = ma
The acceleation accoiated with this centripetal force is
a=v^2/r
the radius is found by r=d/2=5.75m
velocity is found by
v=d/t
distance is the circumference of the circle
c=pi*d=11.5*3.14=36.11m
time=60s/30.6rpm=1.96s
v=36.11/1.96=18.423m/s
plugging this back in to
a=v^2/r=(18.423m/s)^2/5.75m=59.027m/s^2</span>
Resultant: in biomechanics, often resultant vectors are calculated, in which case a single vector is formed by combining (or summing) two or more other vectors. For example, combining horizontal and vertical forces into a resultant force.
Answer:
C) 17.6
Explanation:
A pythagorean theorem calculator is great you can find them online and most will teach you how to do it you only need to put in two sides
