- (a) Calculate the momentum of a 1950 kg elephant charging a hunter at a speed of 7.50 m/s. kg · m/s (b) Compare the elephant's momentum with that of a 0.0400 kg bullet fired at a speed of 600 m/s. (c) What is the momentum in kilograms times meters per second of the 90.0 kg hunter running at 8.00 m/s after missing the elephant? kg · m/sA rock (rock 1) is flying in the sky towards another rock, rock 2. Rock 1 has a mass of 60 kg, and Rock 2 has a mass of 10 kg. Rock 1 is in the sky with a speed of 25 m/s towards Rock 2, and rock 2 is movingtowards Rock 1 in the opposite direction with a speed of 35 m/s. If the two rocks stick together, what is their final velocity? Ignore air resistance and gravity. Is there a change in the kinetic energy of the system? If so, what is it?Question 3, conservation of momentum
