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.

Answer 1

time = distance/speed: 70m / 11m/s

constant speed means no acceleration

Answer 2

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

Answer 3

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?
