Firstly, do necessary calculations, then draw and complete the table in your book or pc, take a photo or make a document in docs or pdf or pptx file and upload as an answer.

A block of mass M = 10 kg is sitting on a surface inclined at angle θ = 45°. Given that the coefficient of static friction is μ_s = 0.5 between block and surface, what is the minimum force F necessary to prevent slipping? 

Calculate the friction coefficient if 100 N is the value of the static frictional force. And a toy car of mass 4 kg is being pushed by a person but it remains at the static position.

How can you reduce the friction in your body?

Calculate the static friction if the actual force acting upon some car of 100kg is 200 N. However, the car remains in the static position. Given is the coefficient of friction, that is, 0.2. (Choose the correct answer)

What are the useful applications of friction in medicine?

Do necessary calculations first, then draw and complete the table in your book or pc, take a photo or make a document in docs or pdf or pptx file and upload as an answer.

Complete the table by using given data.
