Answer:
The velocity is 19.39 m/s
Solution:
As per the question:
Mass, m = 75 kg
Radius, R = 19.2 m
Now,
When the mass is at the top position in the loop, then the necessary centrifugal force is to keep the mass on the path is provided by the gravitational force acting downwards.
where
v = velocity
g = acceleration due to gravity
Answer:
16.45 m/s
Explanation:
Let y be the vertical distance and x be the horizontal distance
We are given that
The altitude of hang glider increasing at the rate=
The shadow of the glider moves along the ground at speed=
We have to find the magnitude of glider's velocity.
We know that
Magnitude of velocity=
Substitute the values
Hence, the magnitude of glider's velocity=16.45 m/s
Power can be expressed by the product of current and voltage. To see this, consider the units of current and voltage:
Where C is coulombs (charge), s is seconds, J is joules (energy), and W is Watts, or power. See that watts are Joules per second, or the time rate of change of energy.
D it is environmental safe
