Dear Student,
Average velocity=total displacement/total time
Total displacement = h
Assuming initial velocity=u=0 and final velocity = v
putting equation of motion,
v=u+at
=>v=gt
=>t=v/g
Assuming initial velocity=u=0 and final velocity = v
putting equation of motion,
v=u+at
=>v=gt
=>t=v/g
v2=u2+2gh
=>v=√2gh
=>v=√2gh
t=√2gh/g
Average velocity= h/(√2gh/g)
=√gh/2 m/s
Average velocity= h/(√2gh/g)
=√gh/2 m/s
Cheers!!

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
