Question

two football players collide head - on in midair while chasing a pass. the first player has a 90.5 kg mass and an initial velocity of 5.10 m/s, while the second player has a 112 kg mass and initial velocity of - 5.2 m/s. what is their velocity (in m/s) just after impact if they cling together? (indicate the direction with the sign of your answer.) m/s

Explanation:

Step1: Apply the law of conservation of momentum

The law of conservation of momentum states that \(m_1v_1 + m_2v_2=(m_1 + m_2)v\), where \(m_1 = 90.5\space kg\), \(v_1=5.10\space m/s\), \(m_2 = 112\space kg\), \(v_2=- 5.2\space m/s\).

Step2: Solve for \(v\)

Substitute the values into the formula:

$$
LATEXBLOCK0
$$

Answer:

\(-0.6\space m/s\)
