before after A red SUV (mass = 2380-kg) coasting east at 15.3 m/s rear ends a purple station wagon (mass = 1340-kg) coasting east at 13.5 m/s. The cars lock bumpers, sticking together anc travel to the east at what speed? Give your answer in m/s to the correct number of significant figures.

Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1750 kg and was approaching at 7.00 m/s due south. The second car has a mass of 900 kg and was approaching at 19.0 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 _______________ m/s   direction ° _________________ counterclockwise from west   (b)How much kinetic energy (in J) is lost in the collision? (This energy goes into deformation of the cars.) ________________________ J

Two 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.)

4) Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 150,000 kg and a velocity of 0.300 m/s, and the second having a mass of 125,000 kg and a velocity of −0.120 m/s. (The minus indicates direction of motion.) What is their final velocity (in m/s)? _____ m/s

A Z Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York; there is negligible friction between his feet and the ice. A friend throws Olaf a ball of mass 0.400 kg that is traveling horizontally at 10.8 m/s. Olaf's mass is 69.7 kg.( Figure 1) 2 masteringphysics.com/mycitemView?assignment ProblemID=189028758&offset=next W S Figure X command A # 3 20 E D C $ B 4 888 R F I % 5 of V 254 FD T G 6 B Part A 20 If Olaf catches the ball, with what speed ty do Olaf and the ball move afterward?

A 980-kg sports car collides into the rear end of a 2500-kgkg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 2.9 mm before stopping. The police officer, estimating the coefficient of kinetic friction between tires and road to be 0.80, calculates the speed of the sports car at impact. Question: What was the speed sports car at impact? v=??

Skier 1 is going by a slippery snowy hill. He has a mass of 20kg, and he issliding the hill at a velocity of 5m/s. His elder brother has a mass of 30kg.His brother is moving slower with a velocity of 2m/s. Skier collides to hisbrother. Then both of them keep going down the hill as one unit. Calculatethe resulting velocity of skier 1

Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1000 kg and was approaching at 4.00 m/s due south. The second car has a mass of 900 kg and was approaching at 15.0 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?

A 1.10 kg falcon catches a 0.120 kg dove from behind in midair. What is their velocity (in m/s) after impact if the falcon's velocity is initially 20.0 m/s and the dove's velocity is 8.00 m/s in the same direction? (Enter the magnitude.) m/s Additional Materials O Reading

Two 3011 kg train cars toward each other (Car A at 0.8 m/s, Car B at -2.13 m/s) on a level track. After they collide and couple together, what is the final velocity of the two-car object? Your answer should be in units of m/s but your should only submit the number for your answer (and don't forget to check your signs
