When an 85.2-kg adult uses a spiral staircase to climb to the second floor of his house, his gravitational potential energy increases by 2.46 x 103 J. By how much does the potential energy of a 18.8-kg child increase when the child climbs a normal staircase to the second floor? M.
Current Attempt in Progress A water slide is constructed so that swimmers, starting from rest at the top of the slide, leave the end of the slide traveling horizontally. As the drawing shows, one person hits the water 5.00 m from the end of the slide in a time of 0.485 s after leaving the slide. Ignore friction and air resistance, find the height H in the drawing. Water slide H Number i -5.00 m- Units <>
