Part b)
Part c)
Part d)
Explanation:
Part a)
Since the gymnast is holding the rope and remains stationary
So total force is balanced on it
so we will have
T = mg
Part b)
Now gymnast start climbing the rope at uniform speed
so here we have
so again we will have same force equation
Part c)
Now gymnast start climbing up the rope at uniform acceleration
so now we will have
Part d)
Now gymnast start sliding downwards with same uniform acceleration
so now we will have
now we have
