Homework Help: Conceptual Uniform Circular motion problem?

  1. May 8, 2015 #1
    1. The problem statement, all variables and given/known data
    This isnt a homework problem, but I was just thinking of the following question:

    Suppose that a merry go round spins with a constant speed (so its radially accelerating towards the center), and a man want to jump onto the merry go-round while its spinning. In what way should the man get on the marry go round so he wont fall?

    2. Relevant equations

    3. The attempt at a solution

    My guess is that when he gets on the merry go round, he should lean towards the center because thats how the merry go round is accelerating. Is that correct? Is there a way to solve this problem using F=ma?

    He needs a tangential velocity to not be suddenly accelerated in a tangential direction.

    He needs a radial force to get/keep him in a circular trajectory. So leaning inwards seems the best thing to do.

    Find a merry go round (or something similar in a play yard) and experiment.

    [edit] "(so its radially accelerating towards the center)" evokes a wrong image.
