A 10-KG block is pulled along a rough horizontal floor by a 12-N force acting at a 30 degrees angle with respect to the horizontal. The block accelerates at 0.1 m/s2. Calculate

A....... the weight of the block

B...... the force of friction acting on the block

C.... the normal force acting in the block

d.........the coefficient of kinetic friction uk

e..... the force of static friction acting on the block if the pulling force must be 20 N acting at 30 degrees in other start the block moving along the floor

F.... the coefficient of static friction Us

Can you do any of these yourself?

Have you ever seen the expression

Weight = M g ?

Do you know how to calculate friction forces and the relationship to friction coefficients?

In part "e", is "in other start" supposed to be "in order to start"?

I would rather advise students who show some sign of thought and effort, and who do not just post or paste assigned questions and expect worked-out answers.
