Question

What is the tangential velocity of a 15 kg mass tied to a string and moving in a circle of radious 10 m, if the period of the orbit is 0.2 seconds?

Answer 1

Answer:

Tangential speed, v = 314.15 m/s

Explanation:

It is given that,

Mass of the object, m = 15 kg

It is moving in a circle of radius, r = 10 m

Time period, t = 0.2 seconds

We need to find the tangential velocity of the object. It is given by :

$v=\dfrac{2\pi r}{t}$

Where

v = tangential speed

$v=\dfrac{2\pi \times 10\ m}{0.2\ s}$

v = 314.15 m/s

So, the tangential speed of the object is 314.15 m/s. Hence, this is the required solution.
