Sean always rides his Harley-Davidson Fat Boy motorcycle at the posted speed limit of 70 mph on the Pennsylvania turnpike. What is the momentum of Sean's parked 303-kg Harley-Davidson Fat Boy?

Momentum = (mass) x (speed)

When it's parked, it has no speed.

So the momentum when it's parked is

(303 kg) x (zero)  =  Zero

are you like autistic or something?

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
