Question 08 Answer the following question: A. Why is sliding friction less than static friction for the same surface? B. A book of mass 1 kg is at rest on the table. Maximum value of static friction is 200 N and sliding friction is 180 N. Now, Answer: i. If we apply a force of 190 N will the body move from rest? ii. If we apply a force of 210 N will the body move from rest? iii. What is the acceleration of the book if I apply 220 N of force? [5 MARKS] |
