An ice skater is gliding horizontally across the ice with an initial velocity of 7.56 m/s. The coefficient of kinetic friction between the ice and the skate blades is 0.0695, and air resistance is negligible. How much time elapses before her velocity is reduced to 2.32 m/s

 7.723s

Explanation:

given data:

initial velocity = 7.56 m/s.

friction = 0.0695.

change in velocity = 2.32 m/s

Solution:

ice to water 1 water to vapour 2 latent heat

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
