Question

A block of mass 37 kg rests on a rough horizontal plane having coefficient of static friction 0.3. Find out the least force required to just move the block horizontally.

Answer 1

Given: m = 37 kg, µ_s = 0.3, g = 9.8 m /s² 

To find : Limiting force (F_L)

Formula : F_L = µ_sN = µ_s mg

Calculation: From formula,

F_L = 0.3 × 37 × 9.8 = 108.8 N

The force required to move the block is 108.8 N.
