Question

A net force of 10.0 N is exerted by Irene on a 6.7-kg cart for 3.0 seconds. What is its acceleration?

Answer 1

`color(blue)(1.49ms^(-2))`

Explanation:

You can use the formula `bb(F=ma)` for this.

A Net force means the sum of all forces acting on the body.

`F="Netforce"`

`10=6.7*a=>a=10/6.7=1.49ms^(-2)`

The 3 seconds has no bearing on this result, it's probably included to test whether you understand the underlying concepts.
