Question

A 50kg refrigerator is being moved across a kitchen floor with an applied force of

300N. There is a known friction force of 50N acting against the motion of the
refrigerator.


What was the acceleration of the refrigerator? [ Select ]
m/s2

Answer 1

5m/s²

Step-by-step explanation:

Given parameters:

Mass of refrigerator = 50kg

Applied force = 300N

Frictional force = 50N

Unknown:

Acceleration of the refrigerator = ?

Solution:

To solve this problem:

Net force = m x a

m is the mass

a is the acceleration

Net force = Applied force - Frictional force

300 - 50 = 50 x a

250 = 50 x a

a = 5m/s²
