Answer:
angular speed of both the children will be same
Explanation:
Rate of revolution of the merry go round is given as
f = 4.04 rev/min
so here we have
here we know that angular frequency is given as
now this is the angular speed of the disc and this speed will remain same for all points lying on the disc
Angular speed do not depends on the distance from the center but it will be same for all positions of the disc
First we have to calculate the time taken to travel the distance 30 m, is
.
Now from equation of motion,
Given, .
As object starts from rest, so u = 0.
Substituting these values in above equation, we get
.
Thus, the acceleration is
