Question

Calculate the momentum pelephant of a 2140 kg elephant charging a hunter at a speed of 7.63 m/s . pelephant= kg⋅m/s Compare the elephant's momentum with the momentum pdart of a 0.0415 kg tranquilizer dart fired at a speed of 619 m/s . pelephant=pdart pelephant>pdart More information is needed to determine how the momentums compare. pelephant

Answer 1

Answer:

Momentum of elephant is greater than momentum of tranquilizer dart

Explanation:

$m_e$ = Mass of elephant = 2140 kg

$m_d$ = Mass of tranquilizer dart = 0.0415 kg

$v_e$ = Velocity of elephant = 7.63 m/s

$v_e$ = Velocity of tranquilizer dart = 619 m/s

Momentum of elephant

$p_e=m_ev_e\\\Rightarrow p_e=2140\times 7.63\\\Rightarrow p_e=16328.2\ N.s$

Momentum of tranquilizer dart

$p_d=m_dv_d\\\Rightarrow p_d=0.0415\times 619\\\Rightarrow p_d=25.6885\ N.s$

So, $p_e>p_d$

Momentum of elephant is greater than momentum of tranquilizer dart
