Question #93c7e

Answer 1

The force is `60" N"`, that is `60` newtons.

Explanation:

Force is mass times acceleration:

Mass = `12" kg"`
Acceleration = `5" m/s^2"`

Force = `(12×5)("kg" × " m/s^2")`
`=60" N"`

What is that "N" thing I magically put in? Check it out:

A newton, abbreviated N, is defined as the force that accelerates one kilogram by one meter per second squared. So when you see `"kg" × " m/s^2"` as above, you replace it with `"N"` for "newton".
