Question

a 4.0 kg mass and a 2.0 kg mass are next to each other on a horizontal frictionless surface. somebody pushes them from the left with a 12.0 n force. what is the acceleration of the masses?

Answer 1

The acceleration of the masses = 2 m/s²

Step-by-step explanation:

When an object of mass m encounters a force F the resultant acceleration a of the object can be determined by the formula
F = ma

Here m = 4 + 2 = 6kg

F = 12 N

Plugging these vales into F = ma ==>

12 = 6a

a = 2 m/s²
