Question

a car covers a semi circular track of radius 5 M per second with constant speed of pi metre per second find the magnitude of average velocity and displacement

Answer 1

Hope this is the correct answer and it will help you

Answer 2

Answer:

The displacement of the car is 10 m and the average velocity is 2 m/s.

Explanation:

Given that,

Radius = 5 m

Velocity $v = \pi\ m/s$

We know that,

The distance is the product of speed and time.

$d = v\times t$

The time is

$t = \dfrac{d}{v}$

$t = \dfrac{\pi r}{\pi}$

$t = r=5$

The displacement of the car is 2r.

So, The displacement = 10 m

The average velocity equal to the displacement divided time.

$v_{av}=\dfrac{10}{5}$

$v_{av}= 2 m/s$

Hence, The displacement of the car is 10 m and the average velocity is 2 m/s.
