Response:
A man applied a force of 500 N. Can he move the wheelbarrow?
The man cannot move the wheelbarrow since the force he applied is insufficient compared to the weight of the barrow when stationary.
B. If another man attempts to assist and exerts 500 N, will they manage to move the wheelbarrow?
No, the combined force they apply equals that of the wheelbarrow at rest with the stones.
C. Another individual observed their effort in pushing the wheelbarrow. He chose to assist by applying a force of 400 N. Will the three of them succeed in moving the wheelbarrow?
Yes, with the collective force of three men, they can now move the wheelbarrow as their total force exceeds that of the barrow loaded with stones.
