A 5 kg bowling ball is moving toward one last bowling pin at a speed of 6 m/s. The bowling pin has a mass of 1 kg and is staying still. After they
collide, they experience an inelastic collision and both the ball and the pin move at some unknown speed.
Equation: mq*V1 + m2*v2 = my*V1,f+ m2*v2,f (different final velocity)
m1*v1 + m2*v2 = m1*vf + m2*vf (Same final velocity)
Question 1
Level 1:
Calculate the momentum for the 5kg bowling ball moving at 6 m/s
Question 2
Level 2:
Which of the following is the correct way to label the conservative of momentum equation?
A: (5kg)*(6 m/s)+(1kg)*(0 m/s)=
(5kg)*(vf) +(6kg)*(vf)
B: (5kg)*(0 m/s)+(1kg)*(6m/s)=
(5kg)*(vf)+(1 kg)*(vf)
C: (5kg)*(6m/s)+(1kg)*(0 m/s)=
(5kg)*(vf)+(1kg)*(6m/s)
D: (5kg)*(6 m/s)+(1kg)*(0 m/s)=
(5kg)*(vf)+(1kg)*(vf)
Question 3
Level 3:
Using the equation you chose before, calculate the final velocities of the bowling ball and the bowling pins.
Level 4: Let’s say that you now use a bowling ball was now 6kg and moving at 12m/s before hitting the bowling pin. The bowling pin is now 2 kg and staying still. Your friend makes a prediction using conservation of momentum. He claims that the bowling ball and the pin must both be moving at 6 m/s after colliding.
Question 4:
You find out that your friend’a claim was inaccurate. Why was their claim correct?
Question 5:
How could you change there initial velocity of the bowling ball to ensure that your friend was correct in the claiming that the final velocity is 6m/s?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
