Question

if a body of mass of 10 kg is moving on a circular path of radius 5 cm and takes 2 minutes for one revolution then find out the speed of the body.​

Answer 1

Answer:

i don't know the answer

Answer 2

Given :

mass(m) = 10kg

Radius(r) = 5cm = 0.05m

time (t) = 2 mins = 120seconds

To find:

Speed (s) of the body

Solution:

We know that speed of an object in circular motion is given by :$s = \frac{circumference}{time}=\frac{2\pi r}{t}$

where r is the radius in m and t is time taken for one revolution , in seconds.

Substituting the values from the given data, we get:

$s = \frac{2\times 3.14\times 0.05}{120}$

      $= 0.0026 m/s$

Speed of the body is therefore 0.0026m/s
