Can someone explain how to solve this?

You must be very creative in these questions:) Try to think of as many formulae as you know for each of the given qualities.


Work = Force * distance (units: Nm = J)

Momentum = Force * time (units: Ns)

In option B, we are given momentum * velocity, so Ns * m/s = Nm

As we can see, Nm is the definition of Joule, so B gives us Newton-meters and thus Joules:)
