[All sоlutiоns must stаrt by writing аn equаtiоn (or equations) from the equation sheet on your paper. The solution must then follow a logical progression from the equation(s) on the equation sheet to the answer(s).] You want to make a pendulum — to do this, you take a heavy ball, and tie it to a 2.00-m string of negligible mass. You then hang this from the ceiling. You then take the ball and bring it 25 degrees from the downward vertical, and let it go from rest. a) What is the work done by gravity during the interval of time starting when you let go of the ball, and ending when it reaches the lowest point in the trajectory? b.) What is the speed of the ball as it moves through the lowest point in the trajectory of the pendulum? Hint: what is the relationship of the initial y-position of the ball to the length of the string, and how does that relate to the length of the y-coordinate and length of the string at the bottom of the trajectory?
[All sоlutiоns must stаrt by writing аn equаtiоn (or equations) from the equation sheet on your paper. The solution must then follow a logical progression from the equation(s) on the equation sheet to the answer(s).] Two toy boxcars collide with one another and bounce off of each other in a collision that lasts 0.088 s. The mass of boxcar 1 is 3.00 kg and the mass of boxcar 2 is 5.00 kg. Prior to the collision, boxcar 1 is moving to the right at 3.00 m/s. After the collision, boxcar 1 is moving to the left at 3.33 m/s and boxcar 2 is moving to the right at 1.11 m/s. a) Draw a diagram of the final state and determine the initial velocity of boxcar 2. [you will scan and submit this after the quiz] b) Was this collision elastic? Prove it! (Use equations). c) Determine the impulse caused by Boxcar 2 pushing on Boxcar 1. [enter the numerical answer below; submit work after quiz] d) Using impulse/momentum principles, determine the magnitude and direction of the force that is exerted on Boxcar 1 by Boxcar 2.
