A bobsled makes a run down an ice track starting at 66 m vertical distance up the hill.If there is no friction,what is the velocity at the bottom of the hill?
A) 27 m/s
B) 36 m/s
C) 44 m/s
D) 54 m/s

Quizplus · Accepted Answer

The potential energy at the top is converted to kinetic energy at the bottom. Using the equation mgh = 0.5mv^2, where g = 9.8 m/s^2 and h = 66 m, we solve for v: v = sqrt(2gh) = sqrt(2*9.8*66) = 36 m/s.
