In a fairground ride a child of mass 37 kg stands against the inside surface of a circular cylinder of radius 3.9m that rotates around its vertical axis of symmetry. The cylinder has an angular speed of 1.3 rad/s and an angular acceleration of 0.12 rad s^-2. What is the radial inward force on the child.

  • Physics -

    M*R*w^2

    w is the angular speed
    M is the mass
    R is the radius

    The angular acceleration doesn't matter in the radial direction.
