The figure shows a top view of an intersection where a traffic accident occurred. Vehicle 1 was traveling eastward while Vehicle 2, traveling northward, ran through a stop sign and crashed into Vehicle 1. The collision was violent. As the vehicles crushed, they became entangled and moved as one, sliding across the intersection and leaving the road. Here are some technical details of the accident: • Vehicle 2 was larger, weighing 50% more than Vehicle 1. • According to a driver following Vehicle 1, it was traveling at the posted speed limit. • Both streets had the same speed limit. It is not known how fast Vehicle 2 was traveling. • The collision caused Vehicle 1 to divert its path by an angle of 0 = 60°, as shown in the figure. • The street was covered with snow and ice, making conditions very slippery. Use the information above to answer the following questions. (I'm expecting the first question to be fairly straightforward, and the second question to be more tricky.) 1. We know that the driver of Vehicle 2 broke the law by failing to stop at the stop sign. Was the driver of Vehicle 2 obeying the speed limit? If not how much faster or slower than the speed limit was Vehicle 2 traveling? You may express your answer similar to the following: 5% faster than the speed limit, or 10% slower than the speed limit. I'm looking for a numerical answer to this question, although you should work it out symbolically.

Question
Transcribed Image Text:The figure shows a top view of an intersection where a traffic accident occurred. Vehicle 1 was
traveling eastward while Vehicle 2, traveling northward, ran through a stop sign and crashed into
Vehicle 1. The collision was violent. As the vehicles crushed, they became entangled and moved
as one, sliding across the intersection and leaving the road. Here are some technical details of the
accident:
• Vehicle 2 was larger, weighing 50% more than Vehicle 1.
• According to a driver following Vehicle 1, it was traveling at the posted speed limit.
• Both streets had the same speed limit. It is not known how fast Vehicle 2 was traveling.
• The collision caused Vehicle 1 to divert its path by an angle of 0 = 60°, as shown in the figure.
• The street was covered with snow and ice, making conditions very slippery.
Use the information above to answer the following questions. (I'm expecting the first question to
be fairly straightforward, and the second question to be more tricky.)
1. We know that the driver of Vehicle 2 broke the law by failing to stop at the stop sign. Was the
driver of Vehicle 2 obeying the speed limit? If not how much faster or slower than the speed
limit was Vehicle 2 traveling? You may express your answer similar to the following: 5% faster
than the speed limit, or 10% slower than the speed limit. I'm looking for a numerical answer
to this question, although you should work it out symbolically.
