let the velocity of the "wooden block+ bullet "(after hit by bullet) be v so 1/2 mv2= mgh we get v2=2*g* (0..05)
so v = sqrt (0.98) = 0.7v2 m/sec
Let velocity of bullet was u,
so 0.01 *u = (5+0.01)*v =>
u = 5 * 0.7v2 /0.01 = 350 m/sec
so v = sqrt (0.98) = 0.7v2 m/sec
Let velocity of bullet was u,
so 0.01 *u = (5+0.01)*v =>
u = 5 * 0.7v2 /0.01 = 350 m/sec

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
