A hockey puck slides with an initial speed of 48 m/s on a large frozen lake. If the coefficient of kinetic friction between the puck and the ice is 0.030, what is the speed of the puck after 11 s?

Answer 1

force=mass*acceleration
acceleration=force/mass=mu*mass*g/mass
= mu*g

Vf=vi-a*t=vi-mu*g*time
