Unformatted text preview: ical energy is conserved here: 1 Eel = E p , k Δx 2 = mgh 2 Δx = 2mgh / k = 2(1kg )(9.8m / s 2 )(0.625m) / (49 N / m) = 0.5m Physics 221 Quiz 6 Name & Section Spring 2013 Quiz 6D A 1.00 ­kg block is falling down on a track from rest at a height of 0.625 m. It drops onto the track smoothly at point B. Then the ball moves along a frictionless circular track (1/4 circle from B to C, radius R = 0.500 m) and a horizontal surface with kinetic friction coefficient µk = 0.100. It moves a distance of Δx on the horizontal surface and then stops....
