The discussion focuses on calculating the final velocity of a cart with a mass of 2 kg when pushed with the same force for 5 seconds, achieving a final velocity of 3 m/s for a 1 kg cart. It clarifies that the relationship between mass and final velocity is not linear; thus, the final velocity of the 2 kg cart cannot simply be half of that of the 1 kg cart. The relevant equations to apply are the SUVAT equations, which account for constant acceleration under the influence of the same force over the same time period.

It isn't quite that simple. In this question, the forces are the same in the two cases and the times are the same. If it had been same forces and same distances the result would be differentNodabove said:is it just half the final velocity because its twice as heavy?
