9. ADDITIONAL QUESTIONS 9.1. A net force F brings about an acceleration a of mass m. What is the new acceleration of mass m if the net force F is halved? ________________________________________________________________ (2) 9.2. A constant resultant force F is applied to objects of masses m and 2m. If the object of mass m accelerates at a, what will the acceleration of the other object be? ________________________________________________________________ (2) 9.3. The sketch below shows two blocks connected by a string of negligible mass that passes over a frictionless pulley also of negligible mass. One block has mass m1 = 2 kg and the other has mass m2 = 4 kg. Will the pulley rotate clockwise or anticlockwise? Explain ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ (3) 9.4 Figure shows a block (mass mA) on a smooth horizontal surface, connected by a thin cord that passes over a pulley to a second block (mB)which h
