Sorry it is impossible to understand your question.

Yes, the angle is when the force of gravity acting parallel to the incline is greater than the force needed to maintain constant speed. This angle is known as the critical angle of incline. At this angle, no amount of horizontal force will be able to keep the mass moving at a constant speed and it will start accelerating down the incline.

A 125.0 kg box is pushed by a horizontal force F at constant speed up a frictionless ramp which makes an angle of 25.0 deg with the horizontal Find the magnitude of the applied force F?
The force F can be determined by balancing the forces acting on the box along the incline. The force of gravity acting downward is mgsin(θ) where θ is the angle of the incline. The force F compensates for this to keep the box moving at a constant speed, so F = mgsin(θ). Plug in the values to find F.
A horizontal force of 100 N pushes a box across a floor at a constant speed. what is the force of friction acting on the box?
The force of friction acting on the box is equal in magnitude but opposite in direction to the applied force, so it is also 100 N. The friction force balances the applied force to keep the box moving at a constant speed.
When a force moves objects over a rough horizontal surface at a constant velocity the work done against friction must?
When a force moves objects over a rough horizontal surface at a constant velocity, the work done against friction must be equal to the work done by the applied force to maintain the constant velocity. This is because the force of friction opposes the motion of the object, so the work done by the applied force must overcome the work done by friction to keep the object moving at a constant speed.
What is the horizontal force when a force of 20N is inclined at an angle of 30 to horizontal?
The horizontal force can be calculated using the formula Fhorizontal = Fcos(θ), where F is the given force (20N) and θ is the angle of inclination (30 degrees). Plugging in the values, we get Fhorizontal = 20N x cos(30) ≈ 17.3N.
What is the value of constant horizontal velocity?
In projectile motion, since , there's no force in the horizontal direction which can change the horizontal motion therefore the horizotal velocity remains conserved Vx=Vox= Vocos theta by using above formula , constant horizontal initial or final velocity can be found. since Initial = final horizontal velocity.
What is the net force acting if an object is moving along a surface with a constant acceleration?
The net force acting on the object is equal to the product of the object's mass and its acceleration. This net force is responsible for maintaining the object's constant acceleration as it moves along the surface.
If a cart is observed moving at a constant velocity along a horizontal frictionless track is there a constant net force acting on it in the direction of motion?
No force is acting on it. Constant velocity means no acceleration, which means no force, from f=ma, no 'a' no force.

A car is moving at a constant speed of 30ms the combined mass of the car and the driver is 1000kg if the driving force is 3000N what is the value of the frictional force?
If the car and driver are moving (along a flat horizontal surface) at constant speed, then there is no acceleration, and the net horizontal force is zero.The applied 3,000N must be canceled by an effective total 3,000N of friction.
If you exert a horizontal force of 600N to slide an object across the floor at a constant speed is the force of friction between the object and the floor greater than less than or equal to 600N?
Since the object is moving at a constant speed, the net force on it must be zero.If I'm applying a constant horizontal force, then the frictional force must be equal to my force = 600N and in the opposite direction to my force.

How can an object accelerate if kinetic friction is equal and opposite to horizontal force which would mean it has a net force of zero?
It wouldn't accelerate. It would move at a constant velocity due to its tendency to keep moving (inertia) and friction being canceled out by the horizontal force.
When a ramp is at a angle of 10.5 degrees what will be the applied force?
The applied force will depend on the required force, and the angle to the ramp (or the horizontal) at which the force is applied.

Why does a force of gravity has no effect on horizontal component of velocity?
The force of gravity only acts vertically, causing objects to accelerate downward. It does not affect the horizontal motion of an object. This means that an object will continue moving horizontally at a constant velocity, unaffected by gravity, as long as no other forces are acting on it in the horizontal direction.
