(B) A maintenance man (climber) tries to maintain one of the power stations iocated at the
top of the mountain in the situation of winter. During his work and by mistake drops his
water bottle which then slides 100 M down the side of a steep icy slope to a point which is
10 m lower than the climber's position. The mass of the climber is 60 kg and his water bottle
has a mass of 500 g.
1) If the bottle starts from rest, how fast is it travelling by the time it reaches the bottom
of the slope? (Neglect friction.)
What is the total change in the climber's potential energy as she climbs down the mountain
to fetch her fallen water bottle? i.e. what is the difference between her potential energy at
the top of the slope and the bottom of the slope? Analysis all the above situation.
