1- Billiard ball A with mass 0.81 kg collides head on and elastically with billiard ball B (same mass) at rest. Knowing that Ball A moved at 3.41 m/s before collision, what is the speed of Ball B after the collision?
2- A 4.78 kg cube sits on a frictionless surface. A 11.99 gram bullet traveling at 388.07 m/s is shot into the brick and they move together at a certain speed. What is the speed in m/s?
3- What is the SI unit for momentum?
1)
In elastic collision if object 2 is at rest.
v2f = 2*m1*v1i / (m1+m2)
v1f = (m1-m2)*v1i/(m1+m2)
when m1=m2
v2f = v1i
= 3.41 m/s
Answer: 3.41 m/s
2)
use conservation of momentum
initial momentum = final momentum
m1*vi = (m1+m2)*vf
11.99*10^-3 kg * 388.07 m/s = (11.99*10^-3 + 4.78)*vf
vf = 0.971 m/s
Answer: 0.971 m/s
3)
SI unit of momentum is
Kgm/s

Part C: Linear Momentum Problem Cl: (Elastic Collision) A billiard ball moving at 3m/s collides elastically with an identical ball at rest. The final speed of the first ball is 2m/s. At what angles to the original direction do the balls move off? that
INITIAL: FINAL: - - - A white billiard ball with mass mw - 1.54 kg is moving directly to the right with a speed of v- 3.31 m/s and collides elastically with a black billiard ball with the same mass m - 1.54 kg that is initially at rest. The two collide elastically and the white ball ends up moving at an angle above the horizontal of 0 - 60' and the black ball ends up moving at an angle...

12) A ball of mass 1 kg travelling right at 2 m/s collides elastically with a ball of mass 2 kg travelling left at 1 m/s. After the collision, what is the total kinetic energy of the two balls? A) OJ D 1
One billiard ball with a mass of 0.50 kg is shot east at 2.5 m/s. A second billiard ball with a mass of 0.25 kg is shot west at 2.0 m/s. The balls have a glancing collision, not a head-on collision, deflecting the first ball by 90% and sending it north at 1.0 m/s. What are the speed of the second ball after the collision? Answer 3.6 m/s Check What is the direction of the second ball after the collision?...
