Two soccer players bump into each other for a brief moment. Player 1 has a mass of 100 kg and player 2 has a mass of 70 kg. They were running at the same speed in opposite directions before they collided head-on. If there are no other forces pushing the players, which of these is true for the magnitude of the impulse each player received? Hint: the collision lasted equally long for each player. O a. It is the same for players 1 and 2 а. O b. It is precisely zero for both players c. It is larger for player 1 than for player 2 O d. It is larger for player 2 than for player 1
A steel ball of mass 0.896 kg, moving with a velocity 1.25 m/s, strikes asecond ball of mass 0.896 kg, initially at rest. The collision is a glancing one,causing the first ball to be deflected by an angle of 62.4, with a speed of 2.55m/s. Determine the velocity of the second ball after the collision, giving bothits speed and direction. Explain why you should not assume this is a perfectlyelastic collision?
