m1u1 = (m1 + m2)v.
Ef = ½ (m1 + m2)v2,
Ei = ½ m1u12.
Fraction of energy lost = (Ei - Ef)/Ei
= 1 - m1/(m1 + m2) = m2/(m1 + m2).

. Because of the rotation of the earth, a plumb bob may not hang exactly along the direction of
the earth’s gravitational pull (its weight) but deviates slightly from this direction. Calculate the
deviation (a) at 40 latitude, (b) at the poles, and (c) at the equator

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
