.5kg
Because the formula for force is Force = mass multiplied by acceleration, so you would divide Force by the acceleration to find your mass.
Answer:
.556 kg
Explanation:
Newton's second law is that force = mass x acceleration, or F = ma.
Let's apply that here.
F = ma
4.0 N = m (7.2 m/s^2)
4.0/7.2 = m
m = .556 kg.
If you're having trouble with units, remember that Newtons are kg*m/s^2, so your mass will be in kilograms.
