Please ensure that ALL questions are answered and in order from the beginning. Make sure writing is clear and organized you will need access to this link for question 9. https://www.walter-fendt.de/html5/phen/collision_en.htm
Provide complete solutions with diagrams and all work shown Question 4: a) A 50.0kg crate is at the top of a ramp that makes a 300 angle with level ground. If the crate starts to slide and the coefcient of kinetic friction between the crate and the ramp is 0.42, what is the acceleration of the crate? b) Draw free-body diagrams for ea ch of the following objects in uniform circular motion State the force(s) pcoviding the centripetal force. - A ball on a string swinging in circles in the vertical plane i. At the top of the circle ii. At the bottom of the circle - A pilot in a plane making a vertical circle in mid-air c) You will be completing and activity to compare static and kinetic coefcient offriction of a coin sliding down a ramp. You will place a coin on a at ramp and being raising one end until the coin just begins to move (this will measure the static friction). You will continue raising the ramp until the coin slides down the ramp at a constant speed (measures kinetic friction) - Begin by creating a free body diagram for the coin when measuring static friction and kinetic friction - Derive an equation for the coefcient of static friction and kinetic friction based on your free body diagrams (this will help you determine what measurements you need to record) - Once you identify what measurements you will require, complete the activity for you coin and ramp - Repeat this activity for the coin and a different ramp Calculate the coefcient of a static and kineticfriction between the coin and both ramps ~ Compare the static and kinetic coefficient of friction for both ramps d) 1.0kg book is sitting on the floor in the classroom. Determine the amount of work a student must do to move it at constant velocity. ~ To a surface 1.5m above the floor 1.5m along the shelfif the coefficient of kinetic friction is 0.5 e) A frictionless 23kg fan sled (a sled forced to move because of the propulsion by the fan) is traveling forward with a velocity of 2.9m/s. The fan sendsan impulse burst of 30.0N for 13.25, adding to the sled's momentum Calculate the impulse that the fan exerts - What is the initial momentum of the fan sled - What is the nal momentum of the fan sled - What is the nal speed of the fan sled Question 9: 1. Ensure all questions are answered a) A hockey piayer of mass 85kg, traveling at 15m/s [N], collides with another player of mass 70kg traveling at 5.0m/s [E]. if the two players lock skates during the collision and are held together, find the resultant velocity of the pair (assume there is no friction) b) A 3.2kg hawk soaring at 20m/s [N] collides with a 0.50kg sparrow flying at 5.0m/s [W]. Ifboth are on the same horizontal plane, find their velocity if the hawk hangs onto the sparrow after the collision. c) A 0.50kg grenade explodes horizontally into three pieces. The first piece has a velocity of 10m/s [N] and a mass of 0.10kg. The second piece has a velocity of 5.0m/s (ledegreesEl and a mass of 0.20kg. Find the velocity of the third piece. d) Go an Elastic and Inelastic Collision. There will be two simulations (one for gelastic collision and one for an inelastic collision). For each simulation, use different masses and velocities and include a screenshot of the simulation with all the values (mass of Wagon 1 and 2), the velocity of Wagon 1 and 2 before/after collision. For each simulation, please provide a full set of calculations (show your steps) to verify the velocities after the collision Question 5: 1. The following requires you to research one topic and present a well-written report - Your report must include all relevant calculations, examples and a thorough discussion of the principles of physics described in this course - Make sure to cite your sources Option 2: A space elevator is viewed as a protentional option to sending payloads into Earth's orbit. Research what is a space elevator and what are its advantages and disadvantages. What will be some challenges in creating a space elevator
