A point starts at the location ( -7,0) and moves CCW along a circle centered at (0,0) at a constant angular speed of 2 radians per second. Lett represent the number of seconds since the point has swept out since it started moving. Draw a diagram of this to make sure you understand the context! a. Suppose the point has traveled for 0.2 seconds (t = 0.2). How many radians would need to be swept out from the 3-o'clock position...

In the figure, particle A moves along the line y = 33 m with a constant velocity v→ of magnitude 3.5 m/s and directed parallel to the x axis. At the instant particle A passes the y axis, particle B leaves the origin with zero initial speed and constant acceleration a→ of magnitude 0.46 m/s2. What angle θ between a→ and the positive direction of the y axis would result in a collision?
