Answer:
Explanation:
We shall apply law of conservation of momentum .
Momentum before impact = momentum after impact
Since they are moving towards the same direction , their momentum will add up .
Total momentum before impact
= 136 x 6 + 100 x 1 = 916 kg m/s .
Total mass of lineman and quarterback = 236 kg , if their velocity after impact be v
their momentum = 236 v
According to law of conservation of momentum
236 v = 916
v = 3.88 m /s
Both of them will move with velocity of 3.88 towards the north .
