A hockey player skates across a rink of length 75m in 8.9 seconds. What is the average speed of the hockey player? The hockey player is moving at a speed of 9.5 m/s. If it takes him 2 seconds to come to a stop under constant acceleration, how far does he travel while stopping?

Respuesta :

The average velocity is given by

[tex]v=\frac{d}{t}[/tex]

Where d is the distance covered and t is the time taken.

For the given case, we have

d = 75 m

t = 8.9 s

[tex]v=\frac{d}{t}=\frac{75}{8.9}=8.43\; \frac{m}{s}[/tex]

Therefore, the average speed of the hockey player is 8.43 m/s

The hockey player is moving at a speed of 9.5 m/s.
