Answer:
Step-by-step explanation:
First, you must observe the figure attached.
You can identify that:
Then, you can solve for the variable "x" in order to find its value. Then, you get that this is:
You can also identify in the figure that:
Since you know the value of "x", you can substitute it into the equation:
Finally, you must solve for the variable "y" in order to find its value. So, you get:

Step-by-step explanation:
<u>Linear Momentum </u>
The momentum of a system of masses m1,m2,m3... with speeds v1,v2,v3,... is given by
When some interactions take place into the system of masses with no external forces interferring, the total momentum is not changed, which means that if the new speeds are v1', v2', v3'... then:
The problem relates the story of Batman (m1=100kg) who is initially assumed at rest and lands on a boat with mass m2=580 kg initially moving at 14 m/s to the positive reference. When the collision takes place, both masses join and a common speed is achieved by the common mass. Applying the conservation of momentum, we have
Since
