You fire a 70-g arrow so that it is moving at 92-m/s when it hits and embeds in a 10-kg wooden block at rest. Determine (a) the velocity of the block after the arrow embeds in it and (b) the increase in internal energy of the system consisting of the arrow and block during this process. Type your answer. Instructions Follow the steps below to solve this problem: 1. Draw a sketch of the situation, labeling all of the physical quantities given in the problem. Identify your system in the sketch. Make sure both the initial and fınal states are represented in your sketch. 2. Draw an impulse-momentum bar chart and a work-energy bar chart for this process. Take the moment right before the arrow reaches the block as your initial state and the moment right after the arrow embeds in the block as your final state. 3. Solve for (a) the velocity of the block after the arrow embeds in it and (b) the increase in internal energy of the system consisting of the arrow and block before and after the collision. Start with general equations and explain what you are doing and why you did what you did. 4. Evaluate your solution. Describe how you evaluated your answer and whether or not you think your answer is reasonable.
