Question

a hockey puck slides across the ice at a rate of 11 m/sec and covers a distance of 70 meters.  How long does it take the puck to travel 70 meters.  also calculate the acceleration of the puck.

Steve · Answer

time = distance/speed: 70m / 11m/s constant speed means no acceleration

bobpursley · Answer

I assume the puck stopped at 70 meters. average speed=11/2 m/s time=distance/avgspeed accleration: Vf^2=vi^2+2ad solve for a

bobpursley · Answer

So the difference in Steve's answer and mine is this: did the puck slide 70 meters and stop, or was it still moving at 70 m?
