Superman (m 100 kg) saves the earth once again by stopping a 20,000 kg asteroid

Question

Superman (m 100 kg) saves the earth once again by stopping a 20,000 kg asteroid that was going to hit the earth by throwing it towards the sun, if Superman applies a force of 40.000 N to the asteroid, what happens to Superman and the asteroid while he is applying the force? The asteroid accelerates at 2 m/s/s and Superman accelerates at 400 m/s/s in the opposite direction O The asteroid accelerates at 2 m/s/s and Superman accelerates at 2 m/s/s in the opposite direction O The asteroid accelerates at 400 m/s/s and Superman accelerates at 400 m/s/s in the opposite direction O The asteroid accelerates at 2 m/s/s and Superman does not accelerate

Explanation / Answer

acceleration of asteroid = force on asteroid / mass of asteroid

= 40000 N / 20000 Kg

= 2 m/s^2

Asteroid will also apply equal force on superman in opposite direction

acceleration of superman = force on superman / mass of superman

= 40000 N / 100 Kg

= 400 m/s^2

Answer: option 1
