    for finding the largest effect we have to find the percentage uncertainty in each of the variables. percentage uncertainty in F =(0.01/19.62)*100 =0.05097% percentage uncertainty in l = (0.002/2.043)*100 =0.0979% percentage uncertainty in d = 2(0.02/0.54)*100 = 7.41% percentage uncertainty...

    vertical component of velocity is zero initially for both balls as they are fired horizontally. (horizontal component of velocity remain same throughout the motion) vertical component of velocity will increase because of gravity (9.81 ms^-2) which is same for both balls so they will both reach...

    using s=ut+0.5gt^2 for distance x, x=0*t1+0.5gt1^2 (since initial velocity =0) x=1/2gt1^2 (eqn 1) for distance x+h, x+h=0*t2+1/2gt2^2 x+h=1/2gt2^2 making x the subject gives x=1/2gt2^2-h (eqn 2) since x=x eqn 2=eqn 1 1/2gt2^2-h=1/2gt1^2 2(1/2gt2^2-h)=gt1^2 gt2^2-2h=gt1^2 gt2^2-gt1^2=2h...
