Answer to Question #156735 in Mechanics | Relativity for Shalize Dookie

Question

An office worker attempts to move a filing cabinet (m = 48 kg). The coefficient of static friction between the floor and the filing cabinet is 0.53. (4 marks)

a) Calculate the normal force acting on the filing cabinet.

b) Calculate the minimum horizontal force that the office worker must apply to the filing

cabinet to JUST move it.

Answer 1

Answer

a) normal force is given

$N= mg=48\times10=480$ Newton

B) horizontal force

$F=\mu N=0.53\times480$

=254.4Newton.
