- 3. A 6.00 kg block is pressed against a vertical wall by a force (F), as shown in the figure below. The coefficient of static friction between the block and the wall is 0.37 and the directional angle 0 for the force is 48°. Determine the magnitude of the force (F) when the block is about to slide up the wall.please answer clearly.the answers on it is wrong, please i need the correct answer like asap, thank you
