A wad of clay of mass mc= 0.2kg is thrown at a speed vc= 30m/s at a stationary toy train car sitting on a horizontal section of track, as is shown in the diagram. The clay sticks to the train after the collision.The toy train has mass mt= 0.4kg. Ignore friction. a)The train car then ascends a 30◦incline that rises a total height of ∆h= 15/4m. What is the speed of the train car once it reaches the top? b) How long does it take to ascend the incline? c)The train car then runs into a spring of total length L= 0.8m and spring constantk= 60N/m. What is the length of the compressed spring the moment the car comes to rest?
