You will need angle of inclination and observe the object motion. Force pushing object up inclined plane is force act against gravity, if the object move at acceleration then the force is more than gravity. You will need to transform distance travel to height using trigonometry from known angle of inclination and calculate acceleration against direction of gravity. Add this extra acceleration to gravity and time the mass you get the force.
So I was just wondering if you could expand on that or tell me an equation that if I only know the angle, the acceleration that they are pushing the block up at , the force of gravity which most people know (9.81 m/s2) and the mass of the block then i could get kinetic force thx
Additional comment
1. Gravity pull down that is mg and incline at angle A
2. Force is on direction of incline plane and against gravity at mg sin(A)
3. At additional acceleration in direction of incline plane e.g. a this excess force is m.a
4. Net force input is m(a+g.sin(A))
if no acceleration observe then it mean a = 0

If A 70 kg cart is pushed for 50 m with a constant velocity upon a 45º frictionless incline Find the work done on the cart?
The work done on the cart is equal to the force applied multiplied by the distance moved in the direction of the force. In this case, since the incline is frictionless, the only force doing work is the force of gravity. The work done would be the force of gravity acting on the cart multiplied by the distance along the incline.
Where would you find a inclined plane on an electric fan?
You would find an inclined plane on the blades of an electric fan. The angle of the blades creates an inclined surface that helps move air efficiently.
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.
How is a screw similar to an inclined plane?
They are both the same because they are divided by the length of incline or screw to get the correct answer.
Two bodies having the same masses m1 equals 30 grams and m2 equals 40 grams are attached to the ends of a string of negligible mass and suspended from a light frictionless pulley find the acceleration?
To find the acceleration, we first need to calculate the net force acting on the system. The net force is the difference between the gravitational force on each mass. Then, we can use Newton's second law (F = ma) to find the acceleration. The acceleration will be the same for both masses since they are connected by the same string.
How do you find the magnitude of the horizontal components of forces?
Find an expression for the magnitude of the horizontal force in the figure for which does not slip either up or down along the wedge. All surfaces are frictionless.

Calculating work on inclined plane?
Formula of work is always { Work= Force x Distance} so you find the force applied and the distance moved then multiply
