Two friends, Joe and Sam, go to the gym together to strength train. They decide to start off with an exercise called flat bench press. Lying flat on a bench with his arms in an extended position, each friend slowly lowers (to his chest) and then raises a barbell back to the starting position. They start off by using a 46.5 kg barbell. Joe is taller than Sam, which means Joe's arms are 68.4 cm long whereas Sam's are 59.8 cm. Calculate the work done by Joe Wjoe when he raises the barbell to finish one repetition. The acceleration due to gravity is 9.81 m/s². Wjoe = J Remember, Sam also does the exercise. How does the amount of work Sam does Wsam lifting the weight compare to that of Joe? Wsam < Wjoe WSam = Wjoe WSam > Wjoe

To apply the principle of work and energy to a system of particles. The principle of work and energy can be extended from one particle to include a system of particles as follows: ∑T1+∑U1−2=∑T2 where ∑T1 is the system's initial kinetic energy, ∑U1−2 is the sum of the work done by all external and internal forces acting on the system's particles, and ∑T2 is the system's final kinetic energy. When the particles either are undergoing only translational motion or are connected by inextensible cables, the internal forces of the particles negate each other; only the external forces are required in the principle of work and energy. When frictional forces are present, the work done by the frictional force is UF=μkNs, where μk is the coefficient of kinetic friction, N is the normal force, and s is the body's displacement. In this equation, the work done by friction represents both the external work of friction and the internal work that is converted into various forms of internal energy, such…

In a science lab, students determined how the mass of a cart affects its gravitational potential energy and its kinetic energy as it rolls down a ramp. One of the students held the small cart at the top of the ramp and released it to roll down the ramp. The cart’s mass is 150 g. The students ran the experiment three times. In the second round, they added a mass of 30 g to the cart. In the third round, 50 more grams were added to the weight of the cart for a total of 80 grams of mass added to the cart. The students gathered the data recorded in the table. Describe how the gravitational potential energy and the kinetic energy of the cart change as the cart rolls down the ramp in simple terms
