Answer:
The power required to operate the tow is 34.75 kW.
Explanation:
Given that,
A ski tow operates on a slope of angle,
Speed of the rope, v = 13 km/h = 3.62 m/s
Number of riders, n = 54
The average mass per rider of 75.0 kg
We need to find the power required to operate the tow. We know that the rate at which the work is done is called power operated by an object.
Here,
or
P = 34.75 kW
So, the power required to operate the tow is 34.75 kW. Hence, this is the required solution.
PART a)
By energy conservation we can say
divide whole equation by mass "m" and plug in all given data
so gymnast will reach the floor with speed 5.21 m/s
PART b)
Now the gymnast bend her knees by 0.1 m and comes to rest
so here we will have
now the force on the gymnast will be
so during landing the force will be 6798.5 N
Answer:
yes
