A 6.4-kg toboggan is kicked on a frozen pond, such that it acquires a speed of 1.8 m/s to the right. The coefficient of friction between the pond and the toboggan is 0.17. Determine the distance that the toboggan slides before coming to rest. Answer: __________ m (round to the nearest hundredth)

Respuesta :

The distance that the toboggan slides before coming to a rest is given by:

[tex]d=\frac{v_0^2}{2a}[/tex]

And the acceleration of the toboggan is given by:

[tex]a=\mu g[/tex]

Then:

[tex]d=\frac{v_0^2}{2\mu g}=\frac{(1.8\frac{m}{s})^2}{2(0.17)(9.8\frac{m}{s^2})}=0.9724...m\approx0.97m[/tex]

Therefore, the distance that the toboggan slides before coming to a rest is approximately 0.97m.
