Problem 1: Using the constant-acceleration equations A. A bacterium is moving with initial velocity 20 %, when it begins to slow down with a constant deceleration of 4- :I: What distance will it cover from the moment it starts decelerating to the moment when it comes to a stop? B. A motor protein accelerates from rest with constant acceleration a for a time interval of 2 s, over which time it travels a distance of 15 pm. If the motor protein continues with this constant acceleration, how far does it travel over the time interval from t = 2 s to t = 4 3? (Don 'tforget to Show all your work
