2. How fast would a 0.25 kg football have to be traveling to have the same momentum as a 0.05 kg bullet travelling 500 m/s?
Their momentum would be equivalent so
M1V1 = M2V2
0.25*v1=0.05(500)
V1=0.05(500)/0.25
V1=100ms
The answer = 100m/s

3. Sarah, who has a mass of 55 kg, is riding in a car at 20 m/s. She sees a cat crossing the street and slams on the brakes! Her seatbelt stops her from flying forward, bringing her to rest in 0.5 seconds. How much force did the seatbelt put on Sarah?
55(20) =F (0.5)
1100=0.5(F)
F=2200N

4. A big league hitter attacks a fastball! The ball has a mass of 0.16 kg. It is pitched at 38 m/s. After the player hits the ball, it is now traveling 44 m/s in the opposite direction. The impact lasted 0.002 seconds. How big of a force did the ballplayer put on that ball? …show more content…
0.16(38) +0.16(44) =f (0.002)
6.08+7.04=F (0.002)
13.12=F (0.002)
F=3530 N

5. Someone fires a 0.04 kg bullet at a block of wood that has a mass of 0.5 kg. (The block of wood is sitting on a frictionless surface, so it moves freely when the bullet hits it). The wood block is initially at rest. The bullet is traveling 300 m/s when it hits the wood block and sticks inside it. Now the bullet and the wood block move together as one object. How fast are they traveling?
0.04(300) =0.5+0.04v
12=0.24v
V=22.22m/s

6. Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. They crash into each other and hold onto each other so that they move as one mass. How fast are they traveling?
55(3) +40-(5) = (55+40)

three quarters did not like the outside preparation. The one quarter liked the outside preparation because they felt that the research gave them more background about the lab they were doing. They could spend the time researching online exactly what the experiment wanted us to do. The other three quarters of the group felt that the labs were too difficult, and that the descriptions on canvas didn't provide enough information to create a procedure. They would prefer to have a procedure given to them. New…

1. What questions (hypotheses) are addressed in the paper? Look in the Abstract. Can we calculate the equilibrium for the entire MgO-SiO2 range? If so, can we use these values to create a phase diagram for these minerals? What minerals are present in this composition range? 2. What are the main conclusions of the paper? Look in the Abstract and Conclusions. The main conclusions of the paper are that the most accurate part of the MgO-SiO2 range to calculate equilibrium is the middle compositions…

It causes the bext axon to open up its gates 5. What is the role of the voltage-gated sodium channels for producing an action potential? The gated channels allow the sodium into the axon which causes the membrane potential above the threshold 6. What is the role of the voltage-gated potassium channels? Potassium gates close after sodium gates close too 7. What would happen if the voltage gated sodium and potassium channels opened a. at the same…

The balance of protons and neutrons in a nucleus determines whether it will be stable or unstable. If the nucleus has too many protons or too many neutrons this will upset the balance. The upset of the balance disrupts the strong nuclear forces and the nucleus becomes unstable. The graph below demonstrates the neutron to proton ratio: From the graph shown many stable nuclei have an equal number of protons to neutrons, these are elements in the lighter sections of the periodic table. The heavier…

Steve Chan- Our third quarter of IB Chemistry focused on quantitative chemistry, atomic structure, and the behavior of electrons in the atom. Much of this quarter focused on lab skills and we did experiments on titration, calculating formulas, flame tests, and using a spectrometer. During the 4th quarter we will looking at the topics of periodic trends, chemical bonding and structure, and organic chemistry. For all students reading the text of the chapter would be very beneficial before new material…
