4. What is the acceleration of a box weighing 666 N if a force of 777 N is applied to it?

Heya!!

For calculate aceleration, lets applicate second law of Newton:

                                                 Δ   Being   Δ

                                              F = Force = 85,5 N

                                                  m = Mass = ?

                                             a = Aceleration = ?

First, lets calculate the mass using weight, for that lets use Newton law:

                                                   Δ   Being   Δ

                                             w = Weight = 666 N

                                            g = Gravity = 9,82 m/s²

                                                   m = Mass = ?

⇒ Let's replace according the formula and clear "a":

⇒ Resolving

Like now we have the mass, lets calculate the aceleration:

⇒ Let's replace according the formula and clear "a":

⇒ Resolving

Result:

The aceleration is 11,445 meters per second squared (m/s²)

Good Luck!!

the higher the current the higher the mag field around it the higher the influence on the compass
