Explanation:
Answer:
h = 16.67m
Explanation:
If the kinetic energy of the cylinder is 510J:


Where the inertia is given by:

Replacing this value:

Speed of the block will therefore be:

By conservation of energy:
Eo = Ef
Eo = 0

So,

Solving for h we get:
h=16.67m
Answer:
is from 9 x 107 m/sec to 27 x 107 m/s
Answer:
P = 34034.2 Watt
Explanation:
As we know that the slope angle is given as

now the weight of the rider along the slope is given as



now total weight of all 53 riders along the slope is given as


now the speed of the rope is given as

now the power required is given as
