    18) v^2=u^2+2gs g=-9.81 (since car is moving upwards and gravity act downwards) v^2=28^2+(2*(-9.81)*22) v^2=352.36 v=18.77= 19 ms^-1

    14) By conservation of momentum, 2 x 2 = 1 x v, v =4 so the 1kg trolley moves 4ms-1 to the right, calculating the total KE of the both trolleys, which is 1/2 x 2 x 2^2 + 1/2 x 1 x 4^2 = 12J assuming no energy is lost, the energy stored in the spring is converted to KE gained by the trolleys, so...

    17) At the bottom height is zero so mgh = zero now going upwards.. 2 block has height = 1 so mg1h 3 block = mg2h 4 block = mg3h Sum up P.E ans is 6mgh 18) efficiency = output power/input power in this case its a generator so output power is P=VI = 230 x 32=7360 input power = E(potential) / time...
