The 10 kg wedge B shown in Figure 7.19 is held at rest on an incline of 30? by stop C when it is struck by the 50 g bullet A, which is traveling horizontally with speed vA = 900 m/s. Assume that the bullet is stopped instantaneously by the block.
a. Calculate the velocity with which the wedge starts up the incline.
b. Assuming gravity acts vertically downward, how high does the block travel before stopping? (Assume zero friction.)
