Question

Charlie wants to move a dresser with a weight of 386 N across her room. Find minimum force to get the dresser moving if the coefficient of static friction is 0.68 and the coefficient of kinetic friction is 0.47

Answer 1

The minimum force required to get the dresser moving is 262.48 N.

Minimum force required to move the dresser

The minimum force required to get the dresser moving must be greater than or equal to static frictional force.

Fs = μs(Fₙ)

where;

• Fₙ is mass of the normal force of the dresser
• μs is coefficient of static frictional force

The normal force on the dresser is equal to the weight of the dresser but in opposite direction.

Fs = 0.68 x 386

Fs = 262.48 N

Thus, the minimum force required to get the dresser moving is 262.48 N.
