What is the velocity of the highest point?

What is the velocity of the highest point?

At the peak itself, the vertical velocity is 0 m/s; the velocity vector is entirely horizontal at this point in the trajectory. These concepts are further illustrated by the diagram below for a non-horizontally launched projectile that lands at the same height as which it is launched.

Which spot on the wheel travels faster?

Actually the outside of a wheel has a faster velocity than the inside. You can see this by putting a mark or something on the inside and outside of a wheel and observing while it turns.

Does the top of a wheel move faster than the bottom?

The spokes near the top of the wheel are more blurred than those near the bottom of the wheel because they are moving faster. The wheel pushes on the ground at a certain speed to move the bike in an opposite direction but with an equal speed.

What makes a wheel roll faster?

The diameter of a larger wheel means that its circumference is larger. So, a larger wheel will actually turn slower, but move a vehicle forward faster than a smaller wheel. The smaller wheel will take less torque to get moving, but the larger wheel will give a faster overall speed.

Why does a wheel stop rolling?

The friction between the wheel and axle will eventually cause the wheel to stop. And even when the wheel is rolling on its own (i.e. it does not have an axle ) the point of contact between wheel and ground is not actually a point. The friction between the wheel and axle will eventually cause the wheel to stop.

How fast is the pebble moving at the moment when it is touching the pavement and in what direction?

When the pebble is at the top of the tire, it is moving at 110mph in the x-direction (horizontal). When it is at the bottom, it is moving at 0 mph in the x-direction. When it is in the centre of the wheel, the centre of the tire translates at 55mph in the x-direction and is moving at 55mph in the y-direction.
