Question

In the diagram below, a 5 kg object is moving with a speed of 10 m/s, and a 10 kg object is moving with a speed of 5 m/s.
Which object in the diagram has more kinetic energy?
Group of answer choices

The 5 kg object has more kinetic energy.

Neither object has any kinetic energy.

The 10 kg object has more kinetic energy.

Both of the objects have the same amount of kinetic energy.

Answer 1

k=mv^2 / 2

Answer 2

Velocity carries greater magnitude.

Answer 3

I have a question if the mass is bigger does the kinetic energy increase? Because in the example it looks like the smaller the mass the more the kinetic energy increases. If that's correct I think the answer is A

Answer 4

A is correct.

And no, mass is directly proportional to K. Just know the formula for K very well, because these types of questions are testing that only.

Answer 5

oh okay

Answer 6

It's not just about the smaller mass...look at the speed. If you calculate K with the 5kg object vs 10kg, 5kg is greater because the velocity is bigger
