Answer:
d. 0.3 N
Explanation:
Force: This is defined as the product of mass of a body and its acceleration.
The S.I unit of Force is Newton (N).
Mathematically Force can be represented as,
F = ma .................. Equation 1
Where F = force, m = mass, a = acceleration.
also
a = (v-u)/t............... Equation 2
Where v = final velocity, u = initial velocity, t = time.
Given: v = 0.60 m/s, u = 0 m/s ( From rest), t= 0.16 s.
Substitute into equation 2
a = (0.60-0)/0.16
a = 3.75 m/s²
Also given: m = 80 g = 0.08 kg.
Substitute into equation 1,
F = 0.08(3.75)
F = 0.3 N.
Hence he average force = 0.3 N
The right option is d. 0.3 N
