1. Points A and B are to be mapped onto a number line according to two equations. The solution to the equation 2/3 A= -24 is the
OleMash [197]
<span>The solution to the equation 2/3 A= -24 is the coordinate of point A.

2/3 A = -24
A = -24 / 2/3
A = -24 * 3/2
A = -72/2
A = -36

The solution to the equation 20=-b/0.5 is the coordinate of point B

20 = -b/0.5
20 * 0.5 = -b
10 = -b
10/-1 = -b/-1
-10 = b

A = -36 and B = -10

The distance between the two letters is 26 units. </span>

A gun mass of 5 kg fired a bullet of mass 10 g with the velocity of 360 km/h. What
klemol [59]

Answer:

The recoil velocity of the gun is 0.72\,\,\frac{km}{h}  and is pointing in opposite direction to the velocity of the bullet.

Step-by-step explanation:

Use conservation of linear momentum, which states that the momentum of the bullet (product of the bullet's mass times its speed) should equal in absolute value the momentum of the recoiling gun (its mass times its recoil velocity).

We also write the mass of the bullet in the same units as the mass of the gun (for example kilograms). Mass of the bullet = 0.010 kg

In mathematical terms, we have:

5\, kg * v= 0.01 \,kg\,* 360\,\frac{km}{h} \\v=\frac{0.01\,*360}{5} \,\,\frac{km}{h}\\v=0.72\,\,\frac{km}{h}
