Question

If a cart of a certain mass has a certain net force exerted on it and its acceleration is 4 m/s2, what happens to the acceleration if the cart's mass doubles?

Answer 1

If the carts mass is doubled the acceleration would be half as much. So it would be 2 meters per second squared.

Answer 2

`a = 2 m/s^2`

Step-by-step explanation:

As per newton's II law we know that

`F_(net) = ma`

net force on the system of mass is always product of mass and acceleration

So we know that if force on the system of mass is constant then product of mass and acceleration will remain conserved always

here we know that initially mass of the system is "m" and some force is exerted on the system then we have acceleration given as

`a = 4 m/s^2`

now for the same force if mass is double then we will have

`m(4 m/s^2) = (2m ) a`

`a = 2 m/s^2`
