Number kg m/s Compare the elephant's momentum with the momentum of a 0.0415 kg tranquilizer dart fired at a speed of 603 m s. O Pelephant>Par Pelephant Part O PelephantPbart More information is needed to determine What is the momentum of the 87.0 kg hunter running at 7.47 m /s after missing the elephant? Number kg m/s Previous ? Give Up & View Solution 0 Check Answer Next Exit Hint

Explanation / Answer

A) Momentum of elephant, P1 = m*v = 1860 x 7.59 = 14117.4 kgm/s

B) Momentum of tranquilizer dart, P2 =0.0415 x 603 = 25 kgm/s

Momentum of elephant > momentum of tranquilizer dart

(c) Momentum of hunter, P3 = 87 x 7.47 = 649.89 kgm/s
