Question

a particle moves with a constant speed u along the curve y=sinx the
magnitude of its acceleration at the point corresponding to x=pi/2

Surbjeet · Answer

y= sinx
dy/dx gives velocity
dy/dx = cosx
then d^2 y/dx^2 gives accleration
d^2y /dx^2 = -sinx
at x= pi/2
d^2y /dx^2 = -sin pi/2
= -1
i e a= -1 m/s^2
