- Consider the two pucks shown in the figure. As they move towards each other, the momentum of each puck is equal in magnitude and opposite in direction. Given that v areen = 12.0 m/s, and mblue is 25.0% greater than m, final speeds of each puck (in m/s), if - the kinetic energy of the system is converted to internal energy? 'green what are the 2 30.0° 30.0 11.225 write the initial momentum of the system to find the blue puck's initial velocity, noting that because the initial Vgreen momenta of the two pucks are equal in magnitude and opposite in direction, they sum to zero. Use the relationship that m, = 1.25 m,. Then, write expressions for the initial and final kinetic energies of the system, set - the initial kinetic energy equal to the final kinetic energy, and solve the initial momentum and final kinetic energy equations for the final speeds. m/s 8.98 Write the initial momentum of the system to find the blue puck's initial velocity, noting that because the initial momenta of the two…Mechanic Physics: Please make sure this is right In the figure, a ball of mass m = 56 g is shot with speed vi = 23 m/s (in the negative direction of an x axis) into the barrel of a spring gun of mass M = 263 ginitially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring. Assume that the increase in thermal energy due to friction between the ball and the barrel is negligible. (a) What is the speed of the spring gun after the ball stops in the barrel? (b)What fraction of the initial kinetic energy of the ball is stored in the spring?Can any real collision ever be truly perfectly elastic? Why or why not? (You should think about this in two ways: first consider what effects of the environment surrounding the collision might have on energy and momentum conservation; second, consider the objects themselves – how must an object react to a collision in order to be considered "perfect"?).
