3. A small object moves on a circle of radius R = 7.87 m. The speed of the object as a function of time is v = c1*t, where cl = 4.84 m/s?. + t=0 a. The object starts at t = 0 on the positive x-axis and moves counterclockwise around the circle. When the object has an angle a = 16.3 degrees with respect to the positive x-axis, measured counterclockwise, what is the direction of the instantaneous velocity vector (with respect to the positive x-axis, measured counterclockwise)? b. What is the magnitude of the instantaneous acceleration vector at time t = 1.05s?
