In order to understand the possible cause of a 'right side stomach pain', it may be helpful to know the organs and structures that exist in this region of the body. Diseases, infections, or irritation of any of these organs will lead to a right side abdominal pain.
At that one instant, its velocity is zero, even though its acceleration is still 9.8 m/secÂ². But velocity cannot REMAIN at zero for any length of time if the acceleration is nonzero.
1 Reasoning: At position 2, the angular speed of the pendulum is constant, so the angular. acceleration is zero. At position 3, the angular acceleration is negative. F. At which position or positions is the acceleration vector ~a almost parallel to the velocity vector ~v. position 2 only. positions 1 and 2. positions 2 and 3 positions 1 and 3. Reasoning: Since the value of instantaneous velocity at the ends point is zero.
