Taking upwards positive,
From the 2nd law of eqn. we get,
0^2 = u^2 – 2*g*40
u = root(800) => 20root(2) m/s
This is the velocity to attain 40 meter distance upwards.

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
