Answer:
2.6 m
Explanation:
From work energy theorem we deduce that
The kinetic energy equals to the work dine against friction energy.
Where m represent mass, v is the velocity, f is the frictional force and d is unknown distance that the player slides.
Making d the subject of the formula then
Then by substituting 450N for f, 65 kg for m and 6 m/s for v we obtain
