The speed of satellite or orbital speed is given by below formula.
V = sqrt (GM/R)
where
G = is the gravitational force
M = earth's mass
R = radius of its orbit.
Solving for the Orbital Speed,
First add the earth's radius to the height of satellite wrt to the earths surface, we have R = 6.59x10^6 m + 4.8 x 10 6 m = 11.39x10^6
Now
V = sqrt ((6.673 x 10-11*5.98x1024 kg)/11.39) =5919 m/s
Given :
A wrecking ball of mass 500 kg hangs form a crane by a cable of length 25 m
this wrecking ball is released from an angle of 40 degrees.
To Find :
The height from the lowest point of the arc.
Solution :
From the attached image we have to find the value of h.
So,
Hence, this is the required solution.
The Hubble Space Telescope is a joint ESA/NASA project and was launched in 1990 by the Space Shuttle mission STS-31 into a low-Earth orbit 569 km above the ground. During its lifetime Hubble has become one of the most important science projects ever. Hope this helps! ~ Autumn :)
