Question

With a mass of 109 kg, Baby Bird is the smallest monoplane ever

Answer 1

Total resultant velocity=5.11-3.27=1.84m/s

• m_1=61.4kg
• m_2=109kg
• v_1=1.84m/s
• v_2=?

$\\ \sf\longmapsto ∆P=P$

$\\ \sf\longmapsto m_1v_1=m_2v_2$

$\\ \sf\longmapsto v_2=\dfrac{m_1v_1}{m_2}$

$\\ \sf\longmapsto v_2=\dfrac{61.4(1.84)}{109}$

$\\ \sf\longmapsto v_2=112.976/109$

$\\ \sf\longmapsto v_2\approx 1.3m/s$
