A force of 162 N is applied to an object causing it to accelerate at a rate of 3.8 m/s^2. What is its mass? A. 0.2 kg
B. 616 kg
C. 43 kg
D. 102 kg

43 kg

Explanation:

Force (F) = 162 N

acceleration (a) = 3.8 m/s²

mass (m) = ?

We know

F = m * a

162 = m * 3.8

m = 162 / 3.8

m = 43 kg

It's mass is 43 kg.
