Question

In a collision, a 15 kg mass moving at 2m/s transfers all of its momentum to a 5kg mass. What is the velocity of the 5kg mass after collision?

Answer 1

Answer:

Speed of 5 kg mass when momentum it transferred to it is 6 m/s

Explanation:

As we know that momentum is the product of mass and velocity of the object

So here we know that

$m = 15 kg$

$v = 2 m/s$

now momentum of this object is given as

$P = (15)(2)$

$P = 30 kg m/s$

Now when it transfer all its momentum into the other object then we have

$P = m' v$

$30 = 5 v$

$v = 6 m/s$

Answer 2

The velocity of the 5kg mass after collision is 6 m/s.

To calculate the momentum of an object it is necessary to relate its mass and its velocity:

                                           $P = m \times v$

So, to calculate the momentum of a 15kg object moving at 2m/s it is necessary to make the following expression:

                                             $P = 15 \times 2$

                                           $P = 30 kgm/s$

As the entire value of momentum is transferred to the 5 kg mass during the collision, we have:

                                           $30 = 5 \times v$

                                            $v = 6m/s$

So, the velocity of the 5kg mass after collision is equal to 6m/s.
