Start at the big tree, and take the instructions
one at a time:
1). Walk 15 west.
2). From there, turn around and walk 2 east.
3). From there, walk 7 more east.
Where are you from the big tree now ?
Aren't you 6 west of it ?
I mean, let's see some common sense here !
The momentum of block B afterwards is 
.
Explanation:
We can solve this problem by applying the principle of conservation of momentum.
In fact, the total momentum before and after the collision must be conserved. Therefore, we can write:
where:
is the initial momentum of block A
is the initial momentum of block B
is the final momentum of block A
is the final momentum of block B
Solving for , we find:
So, the momentum of block B afterwards is .

Answer:
The mechanical advantage of a machine is the ratio of the load (the resistance overcome by a machine) to the effort (the force applied)
Explanation:
There is no unit for mechanical advantages since the unit for both input and output forces cancel out.

Good morning!
Excessive ventilation is harmful because it increases intrathoracic pressure, decreasing venous flow and causing problems in the conduction of heartbeats, since it changes the respiratory pattern. In addition, it can cause occasional problems such as reflux and regurgitation.
Hugs!
