A0.002 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

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.
