q9)  s=ut+ 1/2at^2
s=1/2at^2
2h=at^2
2h= a (t2 ^2 - t1^2)
2h/(t2 ^2 - t1^2) =a

11) speed of approach=speed of separation
uA - uB = vA - vB
different directions lets take this direction -----------> as (+)
so
uA-(-uB)=vA + vB


12) ------------> take as (+)
 m1u1 + m2u2= m1v1 +m2v2
m1 *60 + (m2 * -30) = m1v +m2v       (v is same)
cancel out the "m"
60-30 = 2v
30/2=15
