A block of mass 37 kg rests on a rough horizontal plane having coeffic

1.	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» 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.

Answer»

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.
