Question

A 10-kg block rests on a smooth surface and is subjected to a horizontal force of 6 N. Observer A is in a fixed frame $x$. The block has an initial speed of 5 m/s and travels 10 m, both directed to the right and measured from the fixed frame. Observer B moves at a constant velocity of 2 m/s to the right relative to A (attached to the $x'$ axis). (1) Using the principle of work and energy, determine the final speed of the block as measured by Observer A. (2) Repeat using Observer B's frame, and show that both observ…
