By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Use K=1/2 mv2K=1/2mv2 with the block's initial speed for one trial because the initial speed is the same in all trials. A 5 kg block moves with a constant speed of 10 ms to the right on a smooth surface where frictional forces are considered to be negligible. All experiments have the same change in momentum for the center of mass of the system of two carts. Which of the following equations for the conservation of momentum could a student use to help determine the speed vf of each block after the collision? Three 7.25kg7.25-\mathrm{kg}7.25kg masses are at the corners of an equilateral triangle and located in space far from any other masses. Did the student conduct an experiment in which an elastic collision occurred? In Experiment 1, the object's weight is measured by using an electronic balance once the object has been placed at rest on the balance. If the student doubles the radius of the curve, what happens to the acceleration of the car if the speed remains unchanged? WebHave your responses handy as you go through the rubrics to see how you did! Does the data from the graph support the student's claim? 1. 1.
