Unformatted text preview: H sin ( ) + T W g v 2 2 r = t v 2 Find t v 2 , ( ) = v 2 17.76 ft s = t 0.91 s = Problem 15-107 The roller-coaster car of weight W starts from rest on the track having the shape of a cylindrical helix. If the helix descends a distance h for every one revolution, determine the time required for the car to attain a speed v . Neglect friction and the size of the car. Given: W 800 lb = h 8 ft = v 60 ft s = 375...
