A man pulls a refrigerator using 48 N of force. The refrigerator accelerates 0.35 m/s2. What is the mass of the refrigerator?

Explanation:

Formula

F = m * a

Givens

F = 48 N

a = 0.35 m/s^2

m = ??

Solution

F = m * a                                        Substitute the givens

48 = m * 0.35                                Divide by 0.35

48 / 0.35 = m *0.35/0.35            

137.1 kg = mass
