A horizontal rail is used to move a block weighing 70 kg from A to B. The rollers are mounted on A so that the guiding rail can move horizontally with negligible friction under the action of the constant 200 N force at C. The block is released from the resting place at A, with the spring attached to it with an extended initial amount of x is 0.3 m. The spring has a stiffness of 75 N/m. Using the principle of

Question
![A horizontal rail is used to move a block weighing 70 kg from A to B. The rollers
are mounted on A so that the guiding rail can move horizontally with negligible
friction under the action of the constant 200 N force at C. The block is released
from the resting place at A, with the spring attached to it with an extended initial
amount of x is 0.3 m. The spring has a stiffness of 75 N/m. Using the principle of
work and energy:
i.
determine the velocity of the block when it reaches position B.
ii.
if there is appreciable friction between the block and guiding rail, what need
to be considered during the analysis.
