How much momentum does a #2 kg# object moving at #15 m/s# have?

Answer 1

Julia Aguilar

#30kgms^-1#

momentum = mass X velocity #=2kg*15ms^-1=30kgms^-1#

The momentum of an object is calculated using the formula:

[ \text{Momentum} = \text{mass} \times \text{velocity} ]

Given that the mass of the object is (2 , \text{kg}) and its velocity is (15 , \text{m/s}), the momentum of the object can be calculated as follows:

[ \text{Momentum} = 2 , \text{kg} \times 15 , \text{m/s} = 30 , \text{kg m/s} ]

So, the object has (30 , \text{kg m/s}) of momentum.

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.
