Poster has been reminded to show their work in their OP, instead of having to be reminded of that by other respondents
A particle A moves along a circle of radius ##R = 50 cm## so that its radius vector ##r## relative to the point O (Fig. 1.5) rotates with the constant angular velocity ω = 0.40 . Find the modulus of the velocity of the particle, and the modulus and direction of its total acceleration.
Circular movement equations.
The Attempt at a Solution
I tried to do it bye setting the coordinate system on the point O, but after that I really don't know what to do next.
