A hockey puck ( mass 160 grams ) slides across the ice. It's initial velocity is 10 m/s. If the
coefficient of kinetic friction between the puck and the ice is 0.05, how far will it slide before it
stops?
A hockey puck is hit on a frozen lake and starts moving with a speed of 15.0 m/s. If the

You are driving through the Ouachita Mountains at 12m/s. You see a maple-leaf oak (Quercus acerifolia) crossing the road and hit the brakes, 20m away. The coefficient of kinetic friction between your tires and the road is μ_k = 0.7. Will you strike this endangered broadleaf? Justify your answer with a calculation.Your final answer should be the distance you will travel before coming to a stop.
