In which situation does block m experience a larger acceleration? In case 1, the 10kg mass is hanging from a rope and falling. In case 2, a hand is providing a constant downward force. Assume the rope is massless.
The Attempt at a Solution
The force applied to m in case 1 is 98N. Gravity is acting on both 'm' and 10kg, but since 'm' is on top of a table (which provides a normal force), it's going to have no effect on the system's acceleration. Knowing F=ma, F=10kg(9.8 m/s^2), F=98N. Thus, the force in case 1 is equal to the force in case 2. However, the online quiz I did told me that case 2 has the higher acceleration. How is this possible if the downward force is the same in both situations?
