Question

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

Answer 1

Using Newton's second law, the mass of the refrigerator is calculated as 137.14 kg by dividing the force (48 N) by the acceleration (0.35 m/s2).

Step-by-step explanation:

The mass of the refrigerator can be calculated by applying Newton's second law, which states that the force applied to an object is equal to the mass of the object times its acceleration (F = m * a). Given that the force applied is 48 N and the acceleration is 0.35 m/s2, the mass (m) can be found using the formula m = F / a.

Dividing the force by the acceleration gives us:

m = 48 N / 0.35 m/s2 = 137.14 kg (rounded to two decimal places).

Therefore, the mass of the refrigerator is approximately 137.14 kilograms.

Answer 2

Step-by-step 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
