3. A polar robot at rest needs to move an object radially from 0.25m to 0.75m while rotating around its axis 60 degrees. The object must be at its required location in 2 seconds (it will still be moving at that time). Assuming a constant and during the move, determine: a) The minimum acceleration vector and magnitude at the beginning of the move. b) The minimum acceleration vector and magnitude at the end of the move. Notes: The calculations for scenarios with constant angular acceleration are just like linear constant acceleration scenarios except position is replaced with angle. Thus: 1 0 = 00 +0yt+öt² • The units for the above equation can be in degrees or radians (though, I recommend radians as that is always the safer choice). • The importance of the minimum acceleration is that you are finding the acceleration required for the object to reach its required position at exactly 2 seconds. You could achieve the position faster but that wouldn't be the minimum acceleration. Problem 3: Polar Robot
