Question

A person running in a circular track with 10m/s speed.It is found that he is running with an acceleration 2m/s square,find the radius of the circular track

Answer 1

Answer:

Given,

r=10cm,v=10m/s

And the length of the rigid rod is 1m

So,

Tsinθ= rmv 2...1

Tcosθ=mg....2

Dividing equation 1 by 2 then we get,

tanθ= rgv2

10×10

10 2

=1

θ=tan −1

1=45 0
