A block is pushed up a frictionless incline at an angle of 30° with respect to the horizontal by a force of 50 N parallel to the incline. The block moves 5 meters along the incline. Calculate the work done by the force on the block, and determine whether it is positive, negative, or zero.

If a force is applied for a longer time, what happens to the impulse?

What is the relationship between escape velocity and mass of the central body?

Which variable in the equation s = rθ represents the angle of rotation?

In the context of elastic potential energy, what does `x` represent?

What does the variable $$v$$ represent in the power equation $$P = Fv \cos(\theta)$$?

A block of mass 2 kg is attached to a spring with a spring constant of 200 N/m and is initially compressed by 0.1 m from its equilibrium position. The block is then released from rest on a frictionless surface. Describe the types of energy present in the system at the moment the block passes through the equilibrium position.

A particle moves in a central force field with potential energy U(r) = -α/r + β/r², where α and β are positive constants. At what value of r is the force equal to zero?

What is the primary factor that determines the amount of work done on an object?

A satellite orbits Earth in a circular path. The astronauts inside experience weightlessness because:

A 5.0 kg block rests on a horizontal surface with a coefficient of static friction μs = 0.40. What is the maximum horizontal force that can be applied to the block before it begins to move?

Two identical boxes rest on scales in different locations. Box A is in an elevator accelerating upward at 3 m/s² on Earth. Box B is stationary on a planet with unknown gravitational field strength. If both scales show the same reading, what is the gravitational acceleration on the unknown planet?

A satellite of mass m orbits a planet of mass M in a circular orbit of radius r. If the satellite's mass is doubled while maintaining the same orbital radius, by what factor does the gravitational force between the planet and satellite change?
