Consider the collision of a 1500-kg car traveling east at 20.0 m/s (44.7 mph) with a 2000-kg truck traveling north at 25 m/s (55.9 mph). the cars lock together in such a way as to prevent them from separating or rotating significantly. one second before the collision, the car is located at position (x, y) = (-20,0) m and the truck is located at position (x, y) = (0,-25) m.
1. calculate the x-coordinate of the center of mass of the two-automobile system, xcm, one second before the collision. m
2. calculate the y-coordinate of the center of mass of the two-automobile system, xcm, one second before the m
3. calculate the magnitude of the velocity of the center of mass of the two-automobile system, vcm, one second before the collision. m/s
4. calculate the direction of the velocity of the center of mass of the two-automobile system, vcm one second before the collision. (give you answer in degrees relative to the positive x-axis which points to the east.)
degrees
5. calculate the magnitude of the velocity of the center of mass of the two-automobile system, vcm, immediately after the collision. m/s
6. calculate the direction of the velocity of the center of mass of the two-automobile system, vcm immediately after the collision. (give you answer in degrees relative to the positive x-axis which points to the east.)
