covered by ice. The static friction constant between his shoes and the icy slope surface is equal to f=0,3. Confirm that
the tourist is able to climb the slope within a uniform motion (a), check whether the tourist could accelerate with acc.
a=0,5 m/s2 (b), calculate the maximal degree of the slope incline, by which the tourist could still climb (c).
10. An object with mass M slides on a vertical wall by the action of force F directed with an angle alfa in relation to
the wall. Find the acceleration of the object if the friction constant with wall is equal to f.
11. On the ends of a weightless line put through the pulley, there are two weights with masses M and m (smaller than
M). The lighter object is lower from the heavier one by distance equal to l. After what time both weights will be at the
same height (discard all friction forces).
