A 100 g bullet traweling in the x-direction at 100 m/s strikes a 1 kg wooden block at rest. After the collision, wooden block splits into two parts 2 kg and 8 kg and the bullet is obeerved traveling at a speed of b0 m/s in the x-direction. Assume that the wooden piem, are traveling in tbe x-y plane and the .8 ? piece is traveling 3r to the right of the x-direction If the kinctie cnergics of the wooden pieees are equal after the collision, ) In which direction the 2 kg piece is moving? i) What are the velocities of the two wooden pieess? i) How much kinetie energy is loes during the collision? 2. Two metal blocks have been placed on top of a slanted (30 from the table) track as shown in the given figare Initially 5,0 k block is traveling with a speed of 10 ms king the track and 20 kg is at rest. After the 5.0 kg block traveled 5.0 ?1, it collides with the 2.0 kg block. Thereafter, the 2.0 kg block starts moving with a speed of 6 m/s along the track. If the frictional coefficient between the 5.0 kg block and the traclk s 0.4 what is the veocity of the 5.0 kg block (V) rght after the collision? After the collision k Initially 20 kg z0kg
