Question

If Rodger wants to determine whether a baseball thrown at 100 m/s or a bowling ball thrown at 100 m/s will have more momentum, what is one measurement device he could use to figure this out, without actually throwing either ball?A. a rulerB. a stopwatchC. a balance scaleD. an accelerometer I chose C, I am not completely sure that I’m right

Answer 1

The momentum of an object is given by the product of its mass and its velocity:

$p=mv$

If both objects have the same velocity (in this case, 100 m/s), the object with the greater mass will have the greater momentum.

In order to measure the mass of an object, we can use a balance scale.

Therefore the correct option is C.
