    really...??? amazing.... life is so easy now a day:P... so if i say the distance between by house to urs is 100m.. and if i start from my house to urs at a speed of 10ms-1 and reach at 20ms-1 then the distance i think i travelled must be 100m... to solve the numerical if you are using 10ms-1...

    take the motion the right as positive... now ... whic represent increasing velocity down the slope and then constant velocity till hitting the wall.. the collision was inelastic, so Ek has to be dropped.. which means velocity will decrease... so velocity will be constant but in negative...

    n10.. 15.. retarding force = kv.. f=kv v=f/k.. Ek = 1/2mv^2.. v=f/k.. f=mg.. so 1/2(m)(mg/k)^2... 1/2(m^3)(k^2)

    remove 3 and sin from the eq has they have no units... this gives you L(a^2/P)=QT^2 now put their units.. m(m^2/P)=Qs^2.. by solving this, u will have QP=m^3/s^2... or m^3s^-2.... now search through the answers whose product can give you m^3s^-2.. and its B.. (m^2) * (ms^-2)

    for 16.. the string is stretched full.. so no further downward movement will be observed... this shows minimum kinetic energy... the string is fully stretched, so it has maximum elastic potential energy... ( energy possessed by a body by virtue of compression or stretching.. )
