Solution :
We know that :
Formula for Gravitational force is given by :
where, G is the gravitational constant
M is the mass of the bigger body
m is the mass of the smaller body
r is the distance between the two bodies.
And the formula for the centripetal force is given by :
where, m is the mass of the rotating body
v is the velocity
r is the radius of rotation of the body.
We know that mathematically, the gravitational force is equal to the centripetal force of the body.
Therefore,
Hence derived.
Explanation:
It is given that,
Height of the building, h = 44 m
Initial horizontal velocity,
Initial vertical velocity,
It can be assumed to find the maximum height of the projectile and time taken to reach the maximum height.
The formula for the maximum height is given by :
g is the acceleration due to gravity
The total maximum height, h' = h + H
The formula for the time of flight is given by :
Hence, this is the required solution.
