A hockey puck sliding on a frictionless surface strikes a box at rest. After the collision, the two objects stick together and move at some final speed. (i) Check the statement below (there is only one) which describes the change in momentum and energy of the puck during the collision: The puck loses all of its original momentum, but only loses some (not all) of its mechanical energy. The puck conserves its original momentum and mechanical energy. The puck loses some, but not all, of its original momentum and mechanical energy. The puck loses some, but not all, of its original momentum, but conserves its mechanical energy. The puck conserves its original momentum, and loses some, but not all, of its mechanical energy.

Answer the above statement is ( false );

Answer it orbits high above earth to gain clearer images of light, it magnifies images relative to the human eye, it records most of the universe as it was in the past, not as it is now;

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)
