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.

To determine the horizontal velocity of the pencil relative to the road, we need to consider the motion of the bus and the motion of the pencil separately.

First, let's look at the motion of the bus. We know that the bus is traveling along a straight road at a velocity of 100 km/h. Since the bus is moving in a straight line, we can say that its velocity is purely horizontal in this case.

Now let's focus on the pencil. You are holding the pencil still above your head, which means that its vertical velocity is 0 km/h relative to the bus. However, the pencil is still on the bus and moving along with it.

Since the pencil is moving horizontally with the bus, its horizontal velocity relative to the bus is also equal to the velocity of the bus, which is 100 km/h. This means that relative to the road, the pencil has a horizontal velocity of 100 km/h.

Therefore, the correct answer is b. 100 km/h.
