Hello please help me im new to physics and dont know what to do

  1. Sep 11, 2008 #1
    Starting from rest at the top, a child slides down the water slide at a swimming pool and enters the water at a final speed of 5.00 m/s. At what final speed would the child enter the water if the water slide were twice as high? Ignore friction and resistance from the air and the water lubricating the slide.

    Please help ASAP if you can

    Thanks very much

    Use energy of conservation. Potential energy at top of slide = kinetic energy at bottom. Use the formulas for PE and KE to get final velocity.
