“A 4 kg box is placed on a ramp angled at 20°. The coefficient of static friction between the box and the ramp is 0.35. Will the box slide down the ramp if it starts at rest? Show your calculations and explain your reasoning. (g = 9.8 m/s²) A block with a mass of 6 kg rests on an inclined plane angled at 25°. If the coefficient of static friction between the block and the plane is 0.4, will the block slide down the ramp if it starts at rest? Show your calculations and explain your reasoning. (g = 9.8 m/s²)”
