Question

Calculate the momentum of a 1.90 × 103 kg elephant charging a hunter at a speed of 7.55 m / s.

Calculate the momentum of a 1.90 x103 kg elephant charging a hunter at a speed of 7.55 m /s. Number kg m/s Compare the elephant's momentum with the momentum of a 0.0375 kg tranquilizer dart fired at a speed of 603 ml s. Pelephant > pdart PelephantPdart PelephantPdart O More information is needed to determine More information is needed to determine What is the momentum of the 93.0 kg hunter running at 7.55 m / s after missing the elephant? Number kg m/s

Explanation / Answer

Momentum is given by:

P = m*V

m = mass of object

V = Velocity of object

A.

Momentum of elephant will be:

P = 1.9*10^3*7.55

P = 14345 kg-m/sec

B.

Momentum of dart will be

P = 0.0375*603

P = 22.6125 kg-m/sec

Pelephant > Pdart

C.

Momentum of hunter will be:

P = 93*7.55

P = 702.15 kg-m/sec
