Question

A man pulls a refrigerator using 48 N of force. The refrigerator accelerates 0.35 m/s<2. What is the mass of the refrigerator

Answer 1

Answer: 137.14 kg

Explanation: F=ma (Force = mass x acceleration)

So, 48N (newtons) = m×0.35m/s²

N = kg (m/s²)

(48 kg m/s²)÷0.35m/s² = m

137.14 kg

note: answer is to the nearest hundredth because of the .035 m/s²
