Problem 5: Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1050 kg and is
approaching at 9.5 m/s due south. The second car has a mass of 550 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.
Numeric : A numeric value is expected and not an expression.
v' =
Part (b) Calculate the direction of the final velocity, in degrees south of west, of the cars.
Numeric : A numeric value is expected and not an expression.
Part (c) What is the change in kinetic energy, in joules, for the collision? (This energy goes into deformation of the cars.)
Numeric : A numeric value is expected and not an expression.
