(Solved): Can someone help me with A,B & C? Please and thank you Block 1, of mass \( m_{1}=6.50 \mathrm{~k ...

Block 1, of mass \( m_{1}=6.50 \mathrm{~kg} \), moves along a Part A frictionless alr track with speed \( v_{1}=15.0 \mathrm{~m} / \mathrm{s} \), it collides with block 2 , of mass \( m_{2}=41.0 \mathrm{~kg} \), which was initially at rest. The blocks stick together after the Find the magnitude \( p_{1} \). of the total initial momentum of the two-block system. collision. (Figure -1) Express your answer numerically. Figure 1 of 1 Part B Find \( v_{f} \), the magnitude of the final velocity of the two-block system. Express your answer numerically. What is the change \( \Delta K=K_{\text {final }}-K_{\text {initial }} \) in the two-block system's kinetic energy due to the collision? Express your answer numerically in joules.
