(5%) Problem 14: Physics students design an experiment utilizing a wooden plank propped with a crate at an angle of 10.3 ' above the floor. As shown in the drawing below, a first block, with mass M = 501 g, is held at rest against a spring with a spring constant of 11.5 kN/m that is compressed by 4.05 cm. When the block is released, it slides up the plank a distance of d = 85.4 cm to where it collides with a second block of mass m = 172 g. Due to some embedded magnets, the blocks stick together, and they travel as a unit up the plank, eventually going past the end of the plank a distance _ = 114.6 cm from the original position of the first block. The coefficient of kinetic friction between the blocks and the plank is 0.19. Ignore the finite size of the blocks. in M * 33% Part (a) Calculate the speed, in meters per second, of the first block the instant before it collides with the second block? VA = 8.06 * Attempts Remain 4 33% Part (b) Calculate the speed, in meters per second, of the two blocks an instant after the collision? A 33% Part (c) Calculate the speed, in meters per second, of the two blocks at the instant they reach the end of the plank? Grade Summary
