Question

the distance of a particle from a fixed point O is given by s= 3cos2t + 4sin2t show that the velocity v and the acceleration a are given by v^2 + 4s^2 =100, a+4s=0. Please give me a hint someone!!

Answer 1

This is an algebra problem. Why are you struggling with it?

Find the two derivatives and do the algebra.

v(t) = s'(t) -- Show what you get for this.

a(t) = v'(t) -- Show what you get for this.
