Question

A 30KG block is on the floor and is pushed to the right with a 60N force while the friction is 15N A) how do you know that the friction is pointed to the left? B) draw a force diagram showing all the forces present on the blockPlease help

Answer 1

Step-by-step explanation

Step 1

Diagram

A)Friction is force that resists the sliding or rolling of one solid object over another, so the direction of the friction force must be the opposite of the applied force

Frictional force always acts in a direction opposite to the direction of applied force.

so,if the direction of the force is to the right, the direction of the friction force must be to the left

Step 2

Free body diagram:

A free body diagram is a simplified representation in a problem of an object , and the force vectors acting on it,is a graphical illustration used to visualize the applied forces , so
