Abaseball accelerates downward at 9.8 m/s2. the force pulling the ball downward is 1.4 n. what is the mass of the baseball? show your work.

mass (m) = 0.1429 kg

Explanation:

Given that:

A baseball accelerates downward at 9.8 m/s²

acceleration (a) = 9.8 m/s²

the force pulling the ball downward is 1.4 N

Force (F) = 1.4 N

We are asked to find the mass;

to do that, wwe go by the formula

Force = mass × acceleration

1.4 N = mass (m) × 9.8 m/s²

mass (m) =  

mass (m) = 0.1429 kg   (since 1 N/(m/s²) = 1 kg)
