Find potential energy of a particle

[Hawraa]

can anyone help me in this please .. I'm having difficulity in this physix course

a 0.40 kg particle moves under the influence of a single conservation force. at point A where the particle has a speed of 10 m/s , the potential energy associated with the conservative force is +40 J. as the particle moves from A to B, the force does +25 J of work on the particle. what is the value of the potential energy at point B ?

Welcome to Physics Forums.

We are more than happy to help you, but as per the forum guidelines, you need to show some effort in solving the problem yourself before we can help you.

What have you tried so far?

the problem is i don't know what does " conservative energy" mean .. and I don't know the difference between work and energy :S
