Question

A 2.50 kg wood block is pressed against a vertical wood wall by a force applied 34.9° to the horizontal. If the block is initially at rest, and μs=0.493, what force would you need to apply to begin moving the box up the wall?

Answer 1

Answer is

F = (0.493) [(9.8 × 2.50) cos 30]

F = 10.46N
