a) assuming no energy is loss
loss in PE = gain in KE
mgh=1/2 mv2
m cancel out
(10*0.13*2)1/2=v
v=1.6 ms-1

b) since momentum is conserved
m*1.6 = m*v + m*0.9
m cancel out
1.6=v+0.9
v=0.7

c) inelastic collision since KE has not been conserved

W07 Q 5(a) P2
phi/360=AB/lambda
(60/360) * lambda = AB
AB = 1/6 * 6
     = 1
So it leads or lags behind (question didnt state which) by 1
see attachment

S06 Q6 P2
What part didnt u understand exactly?
