Question

Which has more momentum, a 3 kg mass moving at 9 m/s or a 5 kg mass moving at 5 m/s?

Answer 1

Answer:

3kg mass moving at 9m/s

Explanation:

momentum = mass × velocity

3×9 = 27

5×5=25

so here 27 is greater

Answer 2

Given:-

• a 3 kg mass moving at 9 m/s

• a 5 kg mass moving at 5 m/s.

To Find:-

• Which has more momentum.

Solution:-

The Formula For Momentum is

$p = mass \times velocity$

Therefore you simply multiply mass times velocity for each object.

For,

$3 kg \: mass \: moving \: at \: 9m/s.$

$= > p_{1} = 3 \: kg \times 9m/s = 27 kg . m/s$

For,

$5 kg \: mass \: moving \: at \: 5 m/s.$

$= > p_{2} = 5 kg \times 5 m/s = 25kg. m/s$

∴The momentum of the First object is larger.
