(a) A car traveling due east strikes a car traveling due north at an intersection, and the two move together as a unit. A property owner on the southeast corner of the intersection claims that his fence was torn down in the collision. Should he be awarded damages by the insurance company? Defend your answer, (b) Let the eastward-moving car have a mass of 1.30 ×103-kg and a speed of 30.0 km/h and the northward-moving car a mass of 1.10 × 103-kg and a speed of 20.0 km/h. Find the velocity after the collision. Are the results consistent with your answer to part (a)?

- Two figure skaters are coasting in the same direction, with the leading skater moving at 5.5 m/s and the trailing skating moving at 6.2 m/s. When the trailing skater catches up with the leading skater, he picks her up without applying any horizontal forces on his skates. If the trailing skater is 50 heavier than the 50-kg leading skater, what is their speed after he picks her up?arrow_forwardWhat external force is responsible for changing the momentum of a car moving along a horizontal road?arrow_forwardCheck Your Understanding Would the ball’s change of momentum have been larger, smaller, or the same, if it had collided with the floor and stopped (without bouncing)?

- Two vehicles of masses m1 = 8000 kg and m2 = 82 x 100 kg undergo collision such that they travel together after the collision. If the first vehicle was traveling east with a velocity of 10 m/s and the second vehicle traveling west with a velocity of 9 m/s. Find the final speeds and direction of the two vehicles.arrow_forwardTwo cars collide at an icy intersection and stick together afterward. The first car has a mass of 1200 kg and is approaching at 8.5 m/s due south. The second car has a mass of 550 kg and is approaching at 15 m/s due west. (a) Calculate the magnitude of the final velocity, in meters per second, of the cars. (b) Calculate the direction of the final velocity, in degrees south of west, of the cars. (c) What is the change in kinetic energy, in joules, for the collision? (This energy goes into the deformation of the cars.)arrow_forwardA man claims that he can hold onto a 12.0-kg child in a head-on collision as long as he has his seat belt on. Consider this man in a collision in which he is in one of two identical cars each traveling toward the other at 60.0 mi/h relative to the ground. The car in which he rides is brought to rest in 0.10 s. (a) Find the magnitude of the average force needed to hold onto the child. (b) Based on your result to part (a), is the man’s claim valid? (c) What does the answer to this problem say about laws requiring the use of proper safety devices such as seat belts and special toddler seats?arrow_forward
- A railroad diesel engine coasting at 20 Km/h runs into a stationary flatcar. The diesel engine weighs 10,000 N and the flatcar has a mass of 100 Kg. Assuming the engine and the flatcar couple together, how fast are they moving after the collision?arrow_forwardTwo cars collide at an icy intersection and stick together afterward. The first car has a mass of 1,150 kg and is approaching at 7.46 m/s due south. The second car has a mass of 938 kg and is approaching at 15.7 m/s due west.

(a) Calculate the final velocity (magnitude in m/s and direction in degrees counterclockwise from the west) of the cars. (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 must look for other simplifying aspects.) magnitude direction m/s • counterclockwise from west (b) How much kinetic energy (in J) is lost in the collision?
