Desperate !!! Circular motion 1. The problem statement, all variables and given/known data Particles travels counterclockwise in circles of radius 5m. The accleration vectors are indicated at three specific times. Find the values of v and dv/dt at each time. a. a=20 m/s^2 . vector a points toward the center of the circle, vector v tangent to the circle b. a=30 m/s^2. vector a points toward the center of the circle at a 30 degree angle in the direction of motion ( so imagine the case a, vector a point directly to the center, this case vector a and the vector a in part a creates a 30 degree) c. a= 50 m/s^2. vector a creates a 45 degree angle clockwise with the radius. 2. Relevant equations a=mv^2/s 3. The attempt at a solution I know that it's confusing. Please give some input. if you guys are unclear I can explain more.
