0 N kg} 5 4.5 m/s 2 The balloon cannot lift the package because the upward acceleration is less than the downward acceleration of gravity, 9.80 m/s 2. Alternative calculation: F gravity 5 (10.0 kg)(9.80 m/s 2) 5 98.0 N, which exceeds the upward force b. What is the upward acceleration if the instruments weigh 2.0 kg? F net 5 F lift 2 F gravity ... ................
