Would this also be P=m8v?

anonymous · Answer

p=m*v sorry

anonymous · Answer

You know the mass of skateboarder=45 and the momentum to be attained =264
p=mv

anonymous · Answer

It is asking momentum of skateboarder only and not skateboarder+skateboard. So m is mass of skateboarder only.

anonymous · Answer

so it will be 264=45*v?
I divide the 264 by 45 which i get 5.8?

anonymous · Answer

yes

anonymous · Answer

The closest option i have is 5.5 meters/second.
