Cart A is traveling east when it collides with cart B , which is traveling north. Cart A has a mass of 3.05 k g , and cart B has a mass of 2.10 k g . The two carts travel together as a single object on a horizontal surface at an angle θ relative to due east, as shown above. Question In another trial, the speed of the carts immediately after the collision is 0.60 m/s , and the carts slide 0.24 m on the horizontal surface before coming to rest. The coefficient of kinetic friction between the sliding carts and the surface is most nearly
