As indicated by the derivation, the principle of impulse and momentum is valid for observers in any inertial reference frame. Show that this is so, by considering the block of mass M which rests on the smooth surface and is subjected to horizontal force F. If observer A is in a fixed frame x, determine the final speed of the block at time { t }_{ 1 } if it has an initial speed { v }_{ 0 } measured from the fixed frame. Compare the result with that obtained by an observer B, attached to the x’ axis that moves at constant velocity { v }_{ B } relative to A. Given: M = 10 kg , { v }_{ 0 } = 5 m/s , F = 6 N , { v }_{ B } = 2 m/s , { t }_{ 1 } = 4 s
