A 40 kg ball is pukled to one side until it is 1.5 above itd lowest point. What will be its velocity as it passes through its lowest point

asked by Merely
  1. Is this a SCIENCE question?
    Is the ball PULLED?
    1.5 WHAT above ITS lowest point?

  2. the potential energy at the high point is equal to the kinetic energy at the low point

    m g h = 1/2 m v^2 ... v = √(2 g h)

    the mass is in kilograms , so the height is probably in meters

    v = √(2 * 9.8 * 1.5) m/s
