Explanation:
Hawking was the first to set out a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. He was a vigorous supporter of the many-worlds interpretation of quantum mechanics.
Answer:
minimum muzzle velocity of the dart:
Explanation:
Al t time t=0, the monkey drops and the dart is shot,
For the monkey the general position equation will be:
it starts from rest so , and the acceleration is , so
(1)
it will hit the ground when y = 0:
For the dart first we need to know the time when it reaches the monkey on the horizontal position, for this we have the equation:
In this case, neglecting the air friction acceleration will be 0, and considering the origin on the gun :
(2)
So the time when it hits the monkey would be when x = 70m:
(3)
To hit the monkey before it reaches the ground it must be
