1. At an intersection car A was traveling south and car B was traveling 35° north of east when they slammed into each other. Upon investigation it was found that after the crash the two cars got stuck and skidded off at an angle of 15° north of east. Each driver claimed that he was going at the speed limit of 60 km/h and that he tried to slow down but couldn't avoid the crash because the other driver was going a lot faster. Knowing that the masses of cars A and B were 1000 kg and 1200 kg, respectively, determine (a) which car was going faster, (b) the speed of the faster of the two cars if the slower car was traveling at the speed limit.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

1. At an intersection car A was traveling south and car B was traveling 35° north of east when they
slammed into each other. Upon investigation it was found that after the crash the two cars got stuck and
skidded off at an angle of 15° north of east. Each driver claimed that he was going at the speed limit of 60
km/h and that he tried to slow down but couldn't avoid the crash because the other driver was going a lot
faster. Knowing that the masses of cars A and B were 1000 kg and 1200 kg, respectively, determine (a)
which car was going faster, (b) the speed of the faster of the two cars if the slower car was traveling at the
speed limit.

3. A bomb which is initially at rest explodes into three fragments. Fragment A of known mass ma moves at a known angle of 8 measured clockwise with respect to the positive y-axis with a known speed |val. Fragment B of unknown mass (but let's call it m3 ) moves at a known angle o measured counterclockwise with respect to the negative x-axis with a known speed |is|. A third fragment C of known mass mc moves off along the negative y-axis with an unknown speed (let's call it |vc]). Only the forces between the fragments are significant during the collision. a. Draw a diagram that shows the initial and final states of the bomb fragments. Label the velocity vectors and known angles. b. Define what you would like to include in your system. c. Write a Newton's 2nd Law equation for this system. d. Determine the speed of fragment C and the mass of fragment B in terms of the known quantities.
