A hockey puck is observed to be sliding along a flat frictionless surface at a speed of 42 mm/s. There is no net force acting on the puck. Assuming it doesn't smash into anything, how FAST will the puck be going 2 h later?

Answer 1

Vo = 0.042 m/s.
a = 0.
t = 2 h = 7200 s.
V = Vo + a*t = 0.042 + 0*7200 =
