Question

Formula for Calculating Momentum

Momentum is the impetus gained by a moving object. The formula for momentum is: p = mv
Which of these two objects has more momentum, and how much more does it have?
Object A is a 15 kg rock, flung from an erupting volcano, traveling at 762 meters per second.
Object B is a stone, rolling down a hill, weighing 1200 kg, traveling at 10 meters per second.
The two objects possess the same momentum.
Object A has 471 kg m/s more momentum than Object B.
Object B has 570 kg m/s more momentum than Object A.
Object B has 670 kg m/s more momentum than Object A

Answer 1

P(A) = 15 kg * 762 m/s = 11,400 kg m / s

P(B) = 1200 kg * 10 m/s = 12,000 kg m / s

Object (B) has more momentum

Note: 12000 - 11430 = 670 ignoring significant figures given
