Question

Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at speed 3v, w

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.

    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...

    Two cars of the same mass collide at an intersection. Just before the collision one car is traveling east at 50.0 km/h and the other car is traveling south at 60.0 km/h. If the collision is completely inelastic, so the two cars move as one object after the collision, what is the speed of the cars immediately after the collision? _______ km/h

    Determine expression for the distance the cars will move until they stop if the coefficient of kinetic friction μk between the cars' tires and the road is about the same for both cars. Express your answer in terms of the variables m1, m2, v1, v2, μk, and appropriate constants. A car of mass mi traveling north at a speed of vi collides with a car of mass m2 traveling east at a speed of v2. They lock together after the...
