A body travel the first 1/2 of the total distance with velocity v1 & second 1/2 with v2. Calculate the A.V.?
1 Answer
Vikas TU
Average velocity = total displacement/total time
for first half,
t1 = x/v1
for second half,
t2 = x/v2
total time = t1 + t2
avg. velocity = 2x/(t1+t2) = > 2x/(x/v1 + x/v2) = > 2/(1/v1 + 1/v2) m/s

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
