For elastic:
m1u1+m2u2=m1v1+m2v2 OR you can use the energy conservation formula 

for inelastic
m1u1=m2u2=V(m1+m2)

electricity question:
1.When a battery in a toy car delivers a current of 0.75A, the p.d across its terminals is 1.3 V. when the car's motion is reversed the current delivered by the battery and the p.d. across its terminals becomes 12A and o.80v respectively.
calculate for the battery
a)the emf
b)the internal resistance

2.physics oct nov 2005 q6 part A(explained in detail)
