A 136 kg defensive lineman is about to tackle a 100 kg quarterback. Right before impact, the lineman is moving north at 6.0 m/s and the quarterback is moving
north at 1.0 m/s. Determine the speed and direction of the two players
immediately after the tackle.

3.88 m/s North

Explanation:

We are given that

We have to find  the speed and direction of the two players

immediately after the tackle.

Using linear conservation of momentum

Substitute the values

Direction of  the two players  immediately after the tackle is North.

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
