Problem 8.102

For the Texas Department of Public Safety, you are investigating an accident that occurred early on a foggy morning in a remote section of the Texas Panhandle. A 2012 Prius traveling due north collided in a highway intersection with a 2013 Dodge Durango that was traveling due east. After the collision, the wreckage of the two vehicles was locked together and skidded across the level ground until it struck a tree. You measure that the tree is 35 ft from the point of impact. The line from the point of impact to the tree is in a direction 39 north of east. From experience, you estimate that the coefficient of kinetic friction between the ground and the wreckage is 0.45. Shortly before the collision, a highway patrolman with a radar gun measured the speed of the Prius to be 50 mph and, according to a witness, the Prius driver made no attempt to slow down. Four people with a total weight of 460 lb were in the Durango. The only person in the Prius was the 150-lb driver. The Durango with its passengers had a weight of 6500 lb, and the Prius with its driver had a weight of 3042 lb. (a) What was the Durangos speed just before the collision? (b) How fast was the wreckage traveling just before it struck the tree?

Step-by-Step Solution:
Step 1 of 3

Doppler Effect (20.7) - Frequency is higher when coming towards the listener - Frequency is lower when moving away from listener - Waves “bunch” in the front while the source moves General Equation for f relative to listener: f = f · VsoundVlistener L sound VsoundVsorce Rules: 1) Velocity is measured with respect to the medium 2) Velocities are positive when moving...
