A 500 kg mass is moving with a force of -215 N.
There is a +115 N force due to friction.

What is the acceleration of the mass?

Answer :

Answer:

-0.2 m/s²

Explanation:

According to Newton's second law of motion, the net force (∑F) on an object is equal to its mass (m) times its acceleration (a). The net force is the sum of all the forces on the object. Given the forces and the mass, we can solve for the acceleration.
