one twice the mass of the other‚ experience the same force for the same time. What is their difference in momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact? You have to use the conservation of the

well since the egg broke the moment it landed. Though we managed to calculate the amount of Potential energy at the start and how much kinetic energy it had when it reached the bottom. Things we learned that was relevant to the lab were what Potential Energy and Kinetic Energy was. Potential Energy is stored energy due to objects relative position‚ while Kinetic energy was energy of motion; amount of energy depends on objects mass and velocity. The lab with the roller coaster showed examples of

time proceeded‚ reaching values of 101.81 and 61.67 mg g-1 respectively‚ after 120 h. The opposite behavior was observed concerning the volumetric rates of Cr(VI) and total chromium removal. The pseudo-second order model adequately described the kinetic process of chromium biosorption by avocado shell‚ which suggests that this process chiefly occurs as a result of chemisorption. 1. Introduction Chromium compounds are environmental pollutants occurring in soil‚ water and industrial effluents because

shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic energy an object has can be calculated by the formula: KE = 1/2 MV2 It can be defined as the works needed to accelerate an object of a certain mass from rest to its stated velocity

translating‚ rotating‚ and vibrating in a container. If the molecules are moving around quickly then they have a large sum of kinetic energy which means that they are warm appear warm. But if energy is removed from the molecules start moving slower and if all energy is removed from the molecules then the system that the molecules exist in will have zero energy. When matter has zero kinetic energy means that the matter has a temperature of absolute zero‚ or zero kelvin. It is impossible for anything to be
