Question an ice skater is gliding horizontally across the, Ask an Expert

Academics

Question: An ice skater is gliding horizontally across the ice with an initial velocity of +6.92 m/s. The coefficient of kinetic friction between the ice and the skate blades is 0.0844, and air resistance is negligible.

Part A: How much time elapses before her velocity is reduced to +2.89 m/s?

It'd be really helpful if you could show all steps of your work. Thanks.
