A2 kg mass moving to the right makes an elastic head-on collision with a 4 kg mass moving to the left at 4 m/s. the 2 kg mass reverses direction after the collision and moves at 3 m/s. the 4 kg mass moves 1m/s to the left. what was the initial velocity of the 2 kg mass?

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region
