Question

Q8 A bog is sitting in a Sky swing, which is in
uniform crucular motion of radius of swing
is 7 m, frequercy is 2. Then find distance
travelled by the boy in 5 see​

Answer 1

Answer:We know that maximum tension in vertical circular motion  is at the bottom position where we get

    T−Mg=F  

C

​  

=  

r

Mv  

2

 

​  

     , here F  

c

​  

=centripetal force

     

M

(T−Mg)×r

​  

=v

   v  

2

=  

4

(140−40)×1

​  

=25

   v=5m/s
