Question

write a expression of vehicle along a cercular track​

Answer 1

Answer:

When a boby (vehicle) travelling along a circular path means circumference of a circle then the distance travelled by it be

2\pi \times r2π×r

The time taken to complete the revolution is called Time period.

We know that,

velocity = distance or displacement / Time taken

v=d/t

Now, put the value of d that is circumference of circle

we got:

v = 2\pi \times r \: \: \div \: \: tv=2π×r÷t
