thank u i got it 0.6 i think it's right :D

so i consider the final velocity is zero ?? as the spring compresses to the maximum distance ?

the question is : a 1 kg block at rest on a horizontal surface is connected to an unstreched spring with a spring constant k=1000 N/m . A 2 kg block whose speed is 6 m/s collides with 1kg block. if the two blocks stick together and move on a rough surface after collision: find 1- the final...

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

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...
