A skater with an initial speed of 840 ms stops propelling, Ask an Expert

Academics

A skater with an initial speed of 8.40 m/s stops propelling himself and begins to coast across the ice, eventually coming to rest. Air resistance is negligible.

(a) The coefficient of kinetic friction between the ice and the skate blades is 0.100. Find the deceleration caused by kinetic friction.

(b) How far will the skater travel before coming to rest?
