Calculate the force required to move a block of mass 20 kg resting on

1.	Calculate the force required to move a block of mass 20 kg resting on a horizontal surface, if μs = 0.3 and g = 9.8 m/s2.
Answer» Given: m = 20 kg, μ_S = 0.3, g = 9.8 m/s² To find: Force required (F) Formula: F_S = μ_SN = μ_Smg Calculation: From formula, F_S = 3 × 20 × 9.8 = 58.8N The force required to move the block is 58.8 N.

Calculate the force required to move a block of mass 20 kg resting on a horizontal surface, if μs = 0.3 and g = 9.8 m/s2.

Answer»

Given: m = 20 kg, μ_S = 0.3, g = 9.8 m/s²

To find: Force required (F)

Formula: F_S = μ_SN = μ_Smg

Calculation: From formula,

F_S = 3 × 20 × 9.8 = 58.8N

The force required to move the block is 58.8 N.
