Part A
Find the speed Vfinal of the joined cars after the
collision.
Express your answer in terms of v and ϕ.
Part B
What is the angle theta with respect to north made by the velocity
vector of the two cars after the collision?
Express your answer in terms of phi. Your answer should contain an
inverse trigonometric function.

Problem 12.225 Part A Cars A and B are traveling around the circular race track. At the instant shown, A has a speed of 76 ft/s and is increasing its speed at the rate of 15 ft /s2, whereas B has a speed of 113 ft/s and is decreasing its speed at 25 ft /s2. (Figure 1) Determine the relative velocity of car A with respect to car B at this instant Express your answer to three significant figures and...

3) Figure 3 schematically illustrates a collision between a pair of 1st and 2nd cars having respective masses Mi and M2. The collision occurred on a horizontal plane, the cars did not stick together after the collision, and there was substantial body damage to both cars. The 1st car was initially traveling east with speed Vio. The 2nd car was initially travelling north with speed V2o. The cars collided with each other at an icy intersection and an initial investigation...

Consider the following
two-caraccident: Two cars of equal mass collide at an intersection. Driver E was traveling
eastward, anddriver N, northward. After the collision, the two cars
remainjoined together and slide, with locked wheels, before coming
torest. Police on the scene measure the length of the skid marks to be 9 meters. The coefficient
offriction between the locked wheels and the road is equal to
0.9.
Each driver claims that hisspeed
was less than 14 meters per second (50 mph)....

At the instant shown, cars A and B are traveling at the speeds v A = 21 km/h and vB = 62 km/h . (Figure 1) Figure 1 of 1 100 m Part A If B is accelerating at 1210 km/h? while A maintains a constant speed, determine the velocity of A with respect to B.

Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at speed 2v, while the second was traveling at speed v at an angle phi south of east
(asindicated in the figure). After the collision, the two-car system travels at speed v_final at an angle theta east of
north.Part AFind the speed v_final of the joined cars after the
collision.Express your answer in terms of v and phi.Part BWhat is...

A police department is deciding whether to deploy extra cars to monitor for speeding along a certain stretch of highway. The police department will base its decision on whether more than 20% of vehicles on that stretch travel at speeds greater than 10 miles per hour over the posted speed limit. From a random sample of 150 cars on that stretch of highway, 39 are found to be traveling at speeds greater than 10 miles per hour over the posted...
