Pushing at an angle up an inclined plane

In summary, pushing at an angle up an inclined plane involves applying force at an angle to move an object along the surface. The steeper the incline, the more force is required, and the weight of the object is directly proportional to the force needed. Friction acts against the force and can make it more difficult to push, but pushing at an angle has advantages such as reducing the force needed and distributing weight more evenly.

1. You are pushing a box of mass 18kg with a force of 239 N at 34.7 degrees below the horizontal. The box is on an inclined plane at angle 15 degrees above the horizontal. What is the acceleration of the box up the ramp?



2. F=ma
Fpush-Fgx = ma



The Attempt at a Solution


Fgx = (Fg)(sin(15))
Fpush = (Fg)(cos(34.7))

Fpush - Fgx = ma
145.174 N - 45.702 N = (18kg)(a)
a = 5.5262 m/s/s

Does anybody know how to help me with this?
 

1. What is the concept of pushing at an angle up an inclined plane?

The concept of pushing at an angle up an inclined plane involves exerting force on an object to move it along an inclined surface. This force is applied at an angle to the surface, rather than directly perpendicular or parallel.

2. How does the angle of the incline affect the force required to push an object up the plane?

The steeper the incline, the more force is required to push an object up the plane. This is because the component of the force acting against gravity increases as the angle increases.

3. What is the relationship between the weight of an object and the force required to push it up an inclined plane?

The weight of an object is directly proportional to the force required to push it up an inclined plane. This means that the heavier the object, the more force is needed to move it up the plane.

4. How does friction play a role in pushing at an angle up an inclined plane?

Friction acts in the opposite direction of the force applied to push an object up an inclined plane. This means that it can make it more difficult to push an object up the plane, especially if the surface is rough or the object is heavy.

5. Are there any advantages to pushing an object at an angle up an inclined plane?

Yes, there are several advantages to pushing at an angle up an inclined plane. It can reduce the amount of force needed to move an object, as well as the force needed to overcome friction. It can also help to distribute the weight of the object more evenly, making it easier to push.
