A $70 \mathrm{~kg}$ man standing on ice throws a $3 \mathrm{~kg}$ body horizontally at $8 \mathrm{~m} / \mathrm{s}$. The friction coefficient between the ice and his feet is $0.02$. The distance, the man slips is: (a) $0.3 \mathrm{~m}$ (b) $2 \mathrm{~m}$ (c) $1 \mathrm{~m}$ (d) $\infty$
The friction coefficient between an athelete's shoes and the ground is $0-90 .$ Suppose a superman wears these shoes and races for $50 \mathrm{~m} .$ There is no upper limit on his capacity of running at high speeds. (a) Find the minimum time that he will have to take in completing the $50 \mathrm{~m}$ starting from rest. (b) Suppose he takes exactly this minimum time to complete the $50 \mathrm{~m}$, what minimum time will he take to stop ? $\quad 2$ :
A $100-\mathrm{kg}$ man is sking across level ground at a speed of $8.0 \mathrm{m} / \mathrm{s}$ when he comes to the small slope 1.8 m higher than ground level shown in the following figure. (a) If the skier coasts up the hill, what is his speed when he reaches the top plateau? Assume friction between the snow and skis is negligible. (b) What is his speed when he reaches the upper level if an $80-\mathrm{N}$ frictional force acts on the skis?
