The force is -dU/dy
Is the 3 after the y supposed to be an exponent? If so,
F = -18 y^2 Newtons
Plug in y values to get your answers.
A particle moving along the y-axis has the potential eneryg function U = 6 * y3 J where y is in m. What is the y-component of the force on the particle at 0 m?
What is the y-component of the force on the particle at 9 m?
What is the y-component of the force on the particle at 18 m?
