A hockey puck slides across the ice at a constant velocity. Is the sliding puck in equilibrium? Why or why not?

geniusboy [140]

Answer:

Since the hockey puck is moving at constant velocity

So here we will have

$F_{net} = ma$

where we have

a = acceleration of the object

m = mass of object

so here since we know that acceleration is defined as rate of change in velocity

so here we will say that

$a = \frac{dv}{dt}$

$a = 0$

so we have

$F_{net} = 0$

so we will say that hockey puck is in equilibrium as there is no net force of it
