A praricle performs simple harmonic motiou biween two points A and B which are 10 metres apart on a horizontal straight line. Whecn the particle is 3 metres away from the centre, O, of the line AB, its spced is 8ms'. Find (1) the periodic time of the motion. (ii) the least timo required for the particle to move from B to the midpuint of OA.

Verify the normalization equation 0f(v)dv=1 In doing the integral, first make substitution u=m2kBTv=vvp. This "scaling" transformation gives you all features of the answer except for the integral, which is a dimensionless numerical factor. You'll need the formula 0x2e x 2dx= 4 to find the numerical factor and verify the normalization.`
