help me in physics homework please???

Question

an object is hit, giving it an initial velocity of 4 m/s. If the coefficient of kinetic friction between the ice and puck is 0.05, how far will the puck slide before stopping?
***please show free body diagrams and equations used, thanks!!!!!

Answer 1

The kinetic energy will be lost to the work done by friction, so
.5*m*4^2=m*9.81*0.05*d

solve for d
16.3 m

The FBD has a horizontal force equal to friction, and the normal force in the vertical
