In a conservative field, if the potential energy

U

as a function of position

x

is given as

U=x^3+2 x+3,

then the corresponding conservative force is given by:

View answer and explanation

Correct option: C

-3 x^2-2

Option C (

-3 x^2-2

) is correct because the conservative force is the negative gradient of the potential energy function, which means taking the negative derivative of

U

with respect to

x

.

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
