How long will you collide?

Classical Mechanics Level 4

A ball of mass \(1\textrm{ kg}\) is dropped from a height \(H=2\textrm{ m}\). Estimate how long the ball is in contact with the ground (in seconds)?

Details and assumptions

  • Simplify the question by modeling the ball as an ideal spring of spring constant \(100 \textrm{ Nm}|\).
    • If necessary, take the gravitational acceleration to be \(9.8\textrm{ m/s}^2\).
