Question

Chapter 06, Problem 85 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 time of 0.469 s after leaving the slide. Ignore friction and air resistance, find the height H in the drawing. the slide in a Water slide 5.00 m- Number Units the tolerance is +/-2%

Answer 1

After the swimmer leaves the slide it will execute projectile motion. At point B it was only nowizontal veloury .ut that be UB In projectile motion the body does not accelerate in horizontal direction. so the wonizontal distance. R= not u,t. t =s 0.469 - 10.66 ms. to be at height H from torou energy is - Consider - At ground pout point B a Ens k.6. tpie. swimmer ů at AL A rest so K.E.TO EA = mg Chth) - At B total energy i ú - En K.E.IPE = 1 mo? + mg H. mg CHth) = I no 2+ me tousewation of energy - mogy singh at the type S-228m camin CamScanner
