A pool player uses the cue ball to make a direct hit on the 8-ball. The mass of each ball is 0.17 kg. Before the collision the cue ball moves at 7 m/s and the 8-ball is at rest.
1. Write the equation to find the total momentum before the collision.
2. What is the total momentum of the system before the collision?
3. If the cue ball stops after the collision, how fast does the 8-ball travel? Explain.
4. What is the total momentum after the collision?

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
