Mathematics · Application of Derivatives and Mechanics
An inclined plane is bent in such a way that its vertical cross-section is given by y = x24, where y is in the vertical direction and x is in the horizontal direction (both in meters). If the upper surface of this curved plane is rough with a coefficient of static friction μ = 0.5, the maximum height in cm at which a stationary block will not slip downward is:
- 1100 cm
- 212.5 cm
- 350 cm
- 425 cm✓
