Which has more momentum, a #6kg# object moving at #9m/s# or a #4kg# object moving at #3m/s#?

Answer 1

Nathan Ashcroft

#P_1 > P_2#

#"momentum is given as :"P=m*v# #P_1=6*9=54 k*m/s# #P_2=4*3=12 m/s# #P_1 > P_2#

To calculate momentum, you use the formula: momentum = mass × velocity.

For the first object: momentum = 6 kg × 9 m/s = 54 kg*m/s.

For the second object: momentum = 4 kg × 3 m/s = 12 kg*m/s.

Therefore, the 6kg object moving at 9m/s has more momentum, with 54 kgm/s, compared to the 4kg object moving at 3m/s, which has 12 kgm/s.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
