For any problem where you need to explain your reasoning, use complete sentences, and follow grammar and spelling conventions appropriate to professional science communication. Your work must follow the written solution format described on Canvas. Failure to do so will result in a score of N on the learning target associated with that question. Your work needs to be your own: receiving help from, or working with, anyone else is not allowed. You may use your textbook and notes. 1. (Target M5} A 0.75m long red has a mass of 10 kg. It is pinned down at one end, and allowed to rotate around this pin. A constant force of 25M is applied to the center of the rod. The force is always perpendicular to the rod. What is the rod's angular acceleration? 2. (Target MB} A 4 m long platform hangs suspended from two wires. The platform has a uniformly-distributed mass of 15 kg. A 7kg cat is sitting 0.5 In from the left end of the platform. (a) Where is the center of mass of the platform? Explain your reasoning. (b) You will analyze torque acting on the platform to solve the next part of this problem. What point will you choose to dene the \"axis of rotation\" (sometimes referred to as the reference point) for the measurement of r in your torque calculations? Explain your reasoning. (e) Determine the tension in each wire. 3. [Target K1) An object is released from rest lilm above the ground. After falling for some distance, its speed is lllmfs. (a) How much time did it take to reach that speed? (b) How far did it fall in that time? 4. ('I'argct K2} You accelerate your car from rest to 100 km/hr in 14.124. Assuming constant acceleration, how far did you travel? 5. ['I'arget K3) You kick a. soccer ball so that it leaves the grormd traveling at 12 m/s at a fill\" angle to the ground. If there is a 1.75m tall person standing 2 111, will they be hit by the ball
