Which has more momentum? A 60 kg object traveling at 3 m/s or a 9 kg object traveling at 23 m/s.

If we compare 270 J and 2 380.5 J the higher is 2 380.5 J which is A 9 kg object traveling at 23 m/s

Explanation:

A 60 kg object traveling at 3 m/s

Given:

m = 60 kg

v = 3 m/s

Unknown:

KE or kinetic energy

Formula and solution:

KE = 1/2 mv²

KE = 1/2 (60kg) (3m/s)²

KE = (30kg) (9m²/s²)

Final

KE = 270 kg·m²/s² or simplify as 270 J

A 9 kg object traveling at 23 m/s

Given:

m = 9kg

v = 23m/s

Unknown:

KE or kinetic energy

Formula and solution:

KE = 1/2 mv²

KE = 1/2 (9kg) (23m/s)²

KE = (4.5kg) (529m²/s²)

Final

KE = 2 380.5 kg·m²/s² or simplify as 2 380.5 J

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
