F(x) = 23x⁵ + x³ - 12. What could this be used to find?

• Impulse

• Linear Momentum

• Angular Acceleration

• Potential Energy

A certain one-dimensional conservative force is given as a function of x by the expression F = -kx⁵, where F is in Newtons and x is in meters. A possible potential energy function U for this force is

• U = -5kx⁴

• U = 5kx⁴

• U = -1/5kx⁵

• U = 1/6kx⁶

• U(r) = -Gm₁m₂/r²

• U(r) = Gm₁m₂/r

• U(r) = -Gm₁m₂/r

• U(r) = Gm₁m₂/r²
