the mass of a large car is 1000 kg. how much force would be required to accelerate the car at a rate of 3 m/sec²

3000 N

Explanation:

Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it.

This law can be expresses as F=ma,

where

F - force acting on an object m - the mass of an object a - its acceleration

The more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object's acceleration.

F = ma

F = 1000*3

= 3000 N
