Question

A wooden block of 50 kg at rest on the table. A force of 70 N is required to just slide the

block. The coefficient of static friction is​

Answer 1

Explanation:

Force = Mass ( Acceleration + coefficient of static friction × Acceleration due to gravity )

70 = 50 ( 0 + coefficient of static friction × 9.8 )

70 = 490 × coefficient of static friction

coefficient of static friction = 0.1428 ( approx )
