A volleyball is hit and experiences a net
force of 2 N, which causes it to accelerate at 8 m/s 2. What is the mass
of the volleyball?

0.25 kg

Explanation:

Given that,

net force = 2 N

acceleration of volleyball = 8 m/s

mass of the volleyball = ?

According to the Newton 2nd law of motion, net force depends on the mass of the object and acceleration by which it moves.

i.e Net force = mass x acceleration

2N = mass x 8m/s²

Mass = 2N / 8m/s²

Mass = 0.25 kg

Thus, the mass of the volleyball is 0.25 kg
