Suppose you are standing in the aisle of a bus traveling along a straight road at 100km/h, and you hold a pencil still above your head. Then relative to the bus, the velocity of the pencil is 0km/h, and relative to the road, the pencil has a horizontal velocity of?

a. less than 100km/h

b. 100km/h

c. more than 100km/h

Does the pencil arrive with the bus in a hour? So it must be traveling relative to ground the same as the bus

Since it's Okm/h, if the pencil is relased on the road will it still be Okm/h?

Thanks

I mean it's horizontal velocity.
