You notice a moving body that you find to have an acceleration of 8 m/s2 with a net force of 41 N.

a)Use Newton’s Second Law of Motion (F = m a, m measured in kilograms) to find a linear model that relates acceleration a to force F.

(A) F= .640625 a2

(B) F= 5.125a

(C) F=328/a

(D) F= 2624 /a2

 

b)Using this linear model, find the acceleration of a body with a net force 82 N.
