A cyclist rides around a flat, circular track at constant speed. is the cyclist's acceleration vector zero?

Sagot :

The cyclist's acceleration vector is not zero.

For given question,

A cyclist goes around a level, circular track at constant speed.

We know that , acceleration is the rate at which velocity changes with time, in terms of both speed and direction.

When cyclist move around a circular track with constant speed cyclist's direction of motion changes with time.

This means, cyclist's velocity will change means cyclist's will have acceleration.

And cyclist's acceleration will not be zero.

Therefore, the cyclist's acceleration vector is not zero.
