Question

Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1250 kg and is approaching at 9.5 m/s due south. The second car has a mass of 550 kg and is approaching at 17 m/s due west.Calculate the direction of the final velocity, in degrees south of west, of the cars.What is the change in kinetic energy, in joules, for the collision? (This energy goes into deformation of the cars.)

Answer #1

Two cars collide at an icy intersection and stick together
afterward. The first car has a mass of 1100 kg and is approaching
at 9.5 m/s due south. The second car has a mass of 950 kg and is
approaching at 15 m/s due west.
Part (a) Calculate the magnitude of the final
velocity, in meters per second, of the cars.
Part (b) Calculate the direction of the final
velocity, in degrees south of west, of the cars.
Part (c)...

Two cars collide at an icy intersection and stick together
afterward. The first car has a mass of 1650 kg and was approaching
at 5.00 m/s due south. The second car has a mass of 700 kg and was
approaching at 18.0 m/s due west. (a) Calculate the final velocity
of the cars (In m/s). (Note that since both cars have an initial
velocity, you cannot use the equations for conservation of momentum
along the x-axis and y-axis; instead, you...

Two cars are headed for an intersection. The first car has a
mass of 1218 kg and is approaching at v1 m/s due south. The second
car has a mass of 846 kg and is approaching at 23.9 m/s due west.
The two collide and the intersection and stick together. If the
angle of the velocity after the collision is 20 degrees south of
west, what is the velocity v1?
