Before the asteroid is threw, the total momentum is zero,
since neither Superman nor the asteroid are moving.
Conservation of momentum commands the total momentum after the astronaut is threw
must be zero too. This means that Superman's backward momentum afterward throwing
the asteroid is equivalent to the asteroid forwards momentum, in size.
Momentum is mass times velocity. We know the mass of the asteroid is 1000M and
its velocity is 850 m/s, so its momentum is
(1000M)(850 m/s) = 850,000M m/s.
So to get the answer: dividing by
Superman's mass, M, gives his recoil velocity o 850,000 m/s.
Answer: True
Explanation: A knowledge engineer is a professional who works to improve and builds with the aid of science and also implements advanced logic and AI( artificial intelligence) in computer systems in order to investigate particular issues.
A knowledge engineer also helps tries to emulate the judgements of man.
Since you are part of the team involved in discovering errors in the electronic spread sheet you are a knowledge engineer.
Answer: Heat moves in three ways: Radiation, conduction, and convection.
Answer:
The final velocity of 18 kg ball is 
= 42.09 
Explanation:
Mass of first ball 
= 18 kg
Mass of second ball 
= 47 kg
Initial velocity of 18 kg ball 
= 76
Initial velocity of 47 kg ball = 0
Final velocity of 18 kg ball = ??
Final velocity of 18 kg ball is given by the formula
= 
Put all the values in above formula we get
= 2 × 18 × 
= 42.09
Thus, the final velocity of 18 kg ball is = 42.09
