    Please show the working! I know it's negative, but how do we find the 1st column!?

    The first law follows from the second law: the 2nd law states F=ma , so if F=0 , a=0 the 1st law states that if no resultant forces act on a body it will continue in it's original state of motion or rest , which means there will be no change in velocity , hence a = 0 , which follows from the...

    omg! I didn't notice that! I thought that the total length was 2.5 + 0.5 ! I should look at the markings more often! :%) :)

    How is it 0! , can someones pls show me the directions in which the 3 forces must act in order to produce a resultant of 0!?

    perfectly elastic collision vs elastic collision?

    Is there a difference between them? I think that a perfectly elastic collision is one in which the 2 particles collides, and move away or in the same direction, WITHOUT sticking together, while an elastic collision can be one in which the particles stick together. My book says that the...

    Liquid 1 mass = m volume = v density = p liquid 2 mass = m density = 2p volume = 0.5v ( since the mass must be the same, to "balance" the 2p density, the volume must be half) total density = m/v which is: 2m/0.5v+v ,which works out to 4/3 (m/v) so the...

    How do you get the answer? I tried I=kA^2 , but i I get 4Io then! help! EDIT : I figured it out.
