Help! I don't get this:

( very basic physics science)
It takes force of 300 N to accelerate an empty 100-kg car at 3m/s^2.
If a 160-kg wrestler is inside the car, how much force will be needed to produce the same acceleration?


Answer :

Explanation:

mass of car + mass of the wrestler = (100+160) kg

= 260kg.

force = mass × acceleration

= 260×3 = 780 N.

hope this helps you.
