Block pushed up 35degree incline (frictionless)

In summary, a block pushed up a 35-degree incline refers to an object being moved up a sloped surface at an angle of 35 degrees with respect to the horizontal surface. The term "frictionless" in this context means that there is no force acting against the block as it moves up the incline. The angle of the incline affects the block's movement by increasing the force of gravity and shortening the horizontal distance traveled. The block's speed is not constant and will accelerate as it moves up the incline. The presence of friction can significantly affect the block's movement, requiring a greater force to overcome and can be influenced by the angle of the incline and surface materials.

1. a block is pushed up a 35 degree incline (no friction) by an applied force. If F= 20N and m= 2.0kg, what is the magnitude of the resulting acceleration of the block?



2. not sure?
f=ma




3. don't know where to start. It has been a long time since physics

Welcome to PF.

Start by drawing a free body diagram.

You have gravity of g acting straight down. What component of gravity then is acting down the incline?

And how might this weight component act with respect to the force pushing up the incline?

1. What is a block pushed up a 35-degree incline?

A block pushed up a 35-degree incline refers to an object, typically a rectangular block, being moved up a sloped surface at an angle of 35 degrees with respect to the horizontal surface. This motion is often studied in physics and engineering experiments to understand the effects of different forces on the block's movement.

2. What does "frictionless" mean in this context?

In this context, "frictionless" means that there is no force acting against the block as it moves up the incline. Friction is a force that resists the motion of objects when they are in contact with each other. By assuming a frictionless surface, we can simplify the analysis of the block's movement and focus on other forces, such as gravity and applied force.

3. How does the angle of the incline affect the block's movement?

The angle of the incline affects the block's movement in several ways. As the angle increases, the force of gravity acting on the block will also increase, making it more difficult to push the block up the incline. Additionally, the steeper the incline, the shorter the distance the block will travel horizontally for a given vertical distance. This is because the vertical and horizontal components of the block's movement are related by trigonometric functions.

4. Is the block's speed constant as it moves up the incline?

No, the block's speed is not constant as it moves up the incline. Due to the effects of gravity, the block will accelerate as it moves up the incline. This means that its speed will increase over time until it reaches the top of the incline or is stopped by an opposing force. The rate of acceleration will depend on the mass of the block and the angle of the incline.

5. How does the presence of friction affect the block's movement up the incline?

Friction can significantly affect the block's movement up the incline. In a real-world scenario, there will always be some amount of friction present, which will act against the block's movement. This means that the block will require a greater force to overcome the friction and continue moving up the incline. The angle of the incline and the surface materials can also affect the amount of friction present.
