on a frozen pond , a 12 kg sled is given a kick that imparts to it an initial speed of 7.7 m/s. the coefficient of kinetic friction between sled and ice is 0.1. find the distance of the sled moves before coming to rest . the acceleration of gravity is 9.8m/s . answer in units is m l

Answer 1

the initial energy of the sled is ... 1/2 * 12 * 7.7^2

this energy is dissipated by work against friction over the distance
... d * 12 * 9.8 * 0.1

1/2 * 12 * 7.7^2 = d * 12 * 9.8 * 0.1
