A blue and a green billiard ball, each with a mass of 0.15 kg, collide directly. Before the collision, the blue ball had a speed of 3 m/s while the green ball had a speed of 2 m/s. After the collision, the blue ball stays in place while the green ball continues in motion.

In 3-4 sentences, represent the situation before and after the collision and calculate the speed of the green ball after the collision. Be sure to discuss direction.

The speed of the green ball after the collision will be "1 m/s".

According to the question,

Before collision,

Mass,

[tex]m_1=m_2 = 0.15 \ kg[/tex]

Speed,

[tex]u_1 = 3 \ m/s[/tex]
[tex]u_2 = -2 \ m/s[/tex]

Let,

Blue ball moving in (+) axis.
Green ball moving in (-) axis.
After collision, the final velocity of blue ball be "[tex]v_1[/tex]".

then, [tex]v_2 =0[/tex]

The momentum conversion will be:

→ [tex]m_1 u_1 +m_2 u_2 = m_1 v_1[/tex]

→ [tex]v_1 = u_1 +u_2...(m_1=m_2)[/tex]

→ [tex]v_1 = 3 -2[/tex]

→ [tex]v_1 = 1 \ m/s[/tex] (Speed of green ball)

Thus the above answer is correct.

Answer: The speed of the green billiard ball after the collision is 1 m/s

Explanation:

Mass (Before the collision) m1 and m2 - 0.15 kg

Speed (Before the collision) - u1 = 3 m/s and u2 = -2 m/s

Velocity (After the collision) v1 - final velocity of the blue ball

v2 = 0

m1u1 + m2u2 = m1v1 (momentum conversion)

v1 = u1 + u2 (m1 = m2)

v1 = 3 - 2

v1 = 1 m/s

Let's say the blue billiard ball is going north and the green billiard ball is going west. They would collide directly into each other with the same mass of 0.15 kg. Since the blue billiard ball has the speed of 3 m/s and the green billiard ball has a speed of 2 m/s, you would subtract them to get the velocity after the collision (v1) of the green ball since we already have the velocity before the collision (v2) which equaled zero. The speed of the green billiard ball after the collision is 1 m/s.
