QUESTION:

On a very muddy football field, a 110-kg linebacker tackles an 85-kg halfback. Immediately before the collision, the linebacker is slipping with a velocity of 8.8 m/s north and the half-back is sliding with a velocity of 7.2 m/s east. What is the velocity (magnitude and direction) at which the two players move together immediately after the collision?

QUESTION:

On a very muddy football field, a 110-kg linebacker tackles an 85-kg halfback. Immediately before the collision, the linebacker is slipping with a velocity of 8.8 m/s north and the half-back is sliding with a velocity of 7.2 m/s east. What is the velocity (magnitude and direction) at which the two players move together immediately after the collision?

ANSWER:

Solution 37E To solve this question, we shall have to consider the principle of conservation of momentum. Let us understand the situation from the figure shown below. Therefore, from the question given, the linebacker is moving along the y-axis and the halfback is moving along the x-axis. Let us now now calculate the x and y components of the velocities after the two players start moving together. X-component Let v
