Question

A 0.002 kg arrow with an acceleration of 7.2 m/s2 is flying towards its target. How much force was exerted on the arrow?
a. 0.0036 N
b. 0.0052 N
c. 0.0102 N
d. 0.0144 N

Answer 1

Force, F = ma,            Where F is in N, m is mass in kg,  and a is acceleration in m/s²

mass, m = 0.002 kg,  acceleration a = 7.2 m/s²

Force, F = 0.002 * 7.2 = 0.0144 N

Option D.    

Answer 2

An arrow in flight cannot accelerate, since there's no force on it.
