Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1600 kg and was approaching at 7.00 m/s due south. The second car has a mass of 800 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.

(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 1 300 kg and a speed of 30.0 km/h and the northward-moving car a mass of 1 100 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)?

An 70 kg basketball player lands from a jump and tries to stop her forward motion or momentum. The normal contact force exerted by the floor on her shoes is 2800 N. The frictional force exerted by the floor on her shoes is 800 N and this force acts posteriorly on the player.  There was minimal medial-lateral force during the landing and so this component of the ground reaction force can be ignored. What is the resultant ground reaction force exerted by the floor on the basketball player's shoes?  How many times greater than the player's body weight is this resultant ground reaction force calculated in part a)?

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
