    now it is given that collision is inelastic, it will lose some of its momentum to the wall.. so now change in momentum will be less than 4mv but cant be less than the initial momentum... so the answer is C.

    initial momentum of the ball is 2mv before collision... if collision was perfectly elastic one...

    initial momentum of the ball is 2mv before collision... if collision was perfectly elastic one, all the momentum would have been gained by the ball... and this would have made the change in the momentum equal to 4mv.. 2mv-(-2mv)...

    We add them like circuits. When in series just add 'em. When in Parallel add them like 1/something and inverse it.. ;)

    Case i) When all 3 springs are attached to the load W : So, think.. If you have 3 springs and you have 1 weight attach to them what will be the force for each string ? It would be W/3 So we know F = kx k = W/3x Case ii) When middle spring is removed and 2W load is attached to them : So, think...

    Dushyant, here I took distance XY and XZ and solve them simultaneously. This was the only way I could think of :p ZaqZainab I tried your way now :p LOL Anyways here is my method :¬ Use the equation of motion d = ut + 0.5at^2 equation 1 : 40 = 12u + 72a equation 2 : 80 = 18u + 162a [I added...

    6) The question states that "X is measured with a percentage uncertainty of ±1 % of its value at all temperatures." meaning that the percentage uncertainty is unchanged, so A and B is eliminated. then you need to apply some logic here, will the actual uncertainty get bigger as you approach 100...
