Net Force on 5kg Suitcase and Applied Force Calculation

[Hafsaaa]

Homework Statement

What is the net force acting on a 5kg suitcase when picked up with 60N of force? what is the applied force? What is the acceleration of the suitcase?

Homework Equations

ma=?

The Attempt at a Solution

I'm not even sure on how to start the equation all I know is ma=

The force upwards is 60N, the force downward is simply (5kg)(9.8m/s^2), or weight times gravity to give you force, since gravity is acting on the suitcase.

So, the upward force of 60N minus the downward force of 49N (from 5*9.8), and you get 11N in the positive upward direction.

ma = 11N

a = 11N / 5kg = 2.2 m/s^2 (in the upwards positive direction)
