A player strikes a hockey puck giving it a velocity of 48.83 m/s. The puck slides across
the ice for 0.198 s after which time its velocity
is 46.83 m/s.
The acceleration of gravity is 9.8 m/s

If the mass of the puck is 185 g, what is the
average drag force exerted on it by the ice?

What is the coefficient of kinetic friction for
the puck sliding on ice?

If the puck strikes the goalie’s pads and stops
in a distance of 3.57 cm, what average force is
exerted on the pads?
Answer in units of N.
