Brock
y=sin x,
Differentiate wrt time, dy/dt = cosx dx/dt
Vy=cosx.Vx , at x=pi/2, Vy=0 => Vx=u
Again differentiate wrt time
Ay=cosx.Ax - Vx^2. Sinx, at x=pi/2
Ay=-u^2 and Ax=0(since at that instant body is moving with constant speed in x direction)
Therefore, net acc. magnitude= u^2.

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
