**1.A force of 24 N acts on a body causing its movement on an inclined plane with acceleration 3 m/s^2 . calculate the frictional force.**

so can u illustrate the answer to me?

Thanks

What is the mass in kg? The angle of the plane? The direction of the force?

What is the mass in kg? The angle of the plane? The direction of the force?

No , I just forgot to write the mass which is 5 Kg .This is the All of the Given information.

But for now i have a suggestion and all you have to do is to check w heather I'm right or not.

The net force acting on the system = The force causing the acceleration of the ball - Friction force

right??

well

Net force = 24 - Friction = (5*3)

Net force = 24 - Friction = 15

therefore friction force = 24 - 15 = 9 newtons

Right??

Thanks in advance.

That looks good, provided that the applied 24 N force acts parallel to the plane. Since the problem does not specify that, I guess you'll have to assume it.No , I just forgot to write the mass which is 5 Kg .This is the All of the Given information.
