Batman vs Superman:Games

Batman and Superman played 3 different types of games to know who is stronger......
Instructions:
1. Speed of anything leaving/in batman's hand: 300 km/s.
2. Speed of anything leaving/in superman's hand: 200 km/s
3. Length of rope of superman = 20 km.
4. Length of rope of batman = 500 km.
5. Mass of object=100 kg,mass of car=1000 kg.
6. They are on a planet where g = 100 km/s^2 and radius=500 km Games:

  1. They both are given an asteroid and a tight inelastic,weightless rope. The one with higher frequency of revolutions will win. The revolutions are under gravity i.e the two forces are mg and Tension.
  2. They have to throw an object on a car moving on a circular track of radius 1 km with angular speed 30 rad/s. Those who stop the car will win. Suppose object's velocity is just opposite to car at the time of hitting and object travels in straight line.
  3. They have to throw a ball out of planet's gravitational field.
    Objective:
    No. of games won by batman=A,superman=B; find A*B.

2 solutions

There are 3 games.

Case 1:

Batman or Superman does not win any of the games. Result: 0

Case 2:

Batman wins 1, Superman wins 2 or vice versa. Result: 2

Case 3:

Batman wins 1, Superman wins 1, they both do not win the remaining game. Result: 1

There are 3 cases and there are 3 guesses. Hence, it is guaranteed that at least one of the guesses will be correct.

You haven't understood the question. First game talks of higher frequency which is attained by (v=rw). Batman wins it. Second game talks of momentum conservation. Only onewho can supply enough momentum to stop the object. Batmans velocity is optimum. Thus batman wins second game. Third game talks about escape velocity, which on calculation both cannit supply. Tgus third game is won by none. Answer=1*1=1

It is an anti-solution.

@Prince Loomba One can get the correct answer not by the correct method of working out who won each match, but by gaming the system.

@A Former Brilliant Member Ok. You guessed the answer as you knew it would be among those 3 you mentioned. But you forgot that matches could tie and there will be other solutions also. Anyways, you got the answer.

game 1:superman(v= r * w, w=v/r of superman is more),game 2:batman(momentum of batman's object=30000=-(momentum of car)),game 3:none(escape velocity greater than both speeds). wins=1,1. ans=1.
