Explanation / Answer

I am solving only 1st question. As at one time I can solve one full question at maximum.

1) h = L*(1 - cos) = 35(1 - cos66°) = 20.8 cm

Va = [2gh] = [2*981*20.8] = 202 cm/sec
Vcm = Va*m1/(m1+m2) = 79.63 cm/sec

Relative to the CM:
ub = 79.63 cm/sec
ua = Va - Vcm = 122.37 cm/sec

Vfa = Vcm - ua = -42.74 cm/sec
Vfb = Vcm + ub = 159.26 cm/sec

Hmaxa = Vfa²/(2g) = 0.931 cm
Hmaxb = Vfb²/(2g) = 12.93 cm
