Question

Anne lifts a 9.0 kg barbell with an upward force of 120 N. What is the magnitude of the acceleration of the barbell while Anne is lifting it?

Answer 1

13.33 m/s²

Step-by-step explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

`a = (f)/(m) \\`

f is the force

m is the mass

From the question we have

`a = (120)/(9) \\ = 13.3333333...`

We have the final answer as

13.33 m/s²

Hope this helps you
