# kinematics problem

1. ### Basic Kinematics - shouldn't there be a constant?

1. Homework Statement 2. Homework Equations a=dv/dt, v=dx/dt, x=integ(vdt) 3. The Attempt at a Solution We were given the above problem and solution. Everything seems very straightforward. My question is this: should the function for acceleration also include a constant, e.g. ??? None...
2. ### Really interesting and tough kinematics problem

1. Homework Statement Three ants A, B and C are crawling on a large horizontal tabletop always occupying vertices of an equilateral triangle, size of which may vary with time. If at an instant, speeds of A and B are vA and vB, prove that vC>= vA+vB. 2. Homework Equations Well, that's what I...
3. ### Kinematics chase problem

1. Homework Statement Starting from the center of a circular path of radius R, a particle P chases another particle Q that is moving with a uniform speed v on the circular path. The chaser P moves with a constant speed u and always remains collinear with the centre and location of the chased...
