Rebecca is pushing her motorcycle down the road to a repair shop with a certain net force. If the net force is doubled, by how much does the acceleration change?

If the net force is doubled the acceleration change in the same proportion, that is to say, it is doubled too.

Explanation:

We have that:

From the equation above we see that the acceleration is directly proportional to the force, so hence if the force is doubled:

Therefore, If the net force is doubled the acceleration change in the same proportion, that is to say, it is doubled too.

I hope it helps you!

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
