A hockey puck has an initial velocity of 44 m/s and a final velocity of 34 m/s.

(a) If it travels 25 m during this time, what is the acceleration?
m/s2

(b) If the mass of the puck is 0.13 kg, what is the horizontal force on the puck?
N

1 answer

a) Vf^2=Vi^2+2ad solve for a.
b) force=mass*accelearation
