An 80-kg quarterback jumps straight up in the air right before throwing a 0.43-kg football horizontally at 15 m/s . How fast wil

viktelen [127]

Answer:

The speed of the quarterback backward is $v_q = 0.08 \ m/s$

Known are

$m_Q , m_B , (v_{Bx})_i (v_{Qx})_f, (v_{Bx})_f$

Unknown

$(v_{Qx})_f$

Explanation:

From the question we are told that

The mass of the quarterback is $m_Q = 80 \ kg$

The mass of the ball is $m_B = 0.43 \ kg$

The speed of the ball is $v_{B x}= 15 \ m/s$

The law of momentum conservation can be mathematically represented as

$m_Q u_{Qx} + m_Bu_{Bx} = - m_{Q} v_{Qx} + m_B v_{Bx}$

Now at initial both ball and quarterback are at rest and the negative sign signify that the quarterback moved backwards after throwing the ball

$m_Q v_{Qx} = m_B v_ {Bx}$

=> $v_{Qx} = \frac{m_Bv_{Bx}}{m_Q}$

substituting values

$v_q = \frac{0.43 * 15}{80}$

$v_q = 0.08 \ m/s$
