A sled starts from rest at the top of a snow-covered incline that makes an angle of φ = 16.1 degrees with horizontal. After sliding a distance d = 52 m down the slope, the speed of the sled is s = 14.1 m/s. Write an expression for the coefficient of kinetic friction in terms of the symbols introduced in the problem statement and g (the acceleration due to gravity).

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.

Based on this activity, is kinetic energy always transformed into potential energy?
