Question

Two masses of 1 kg and 2 kg were dropped from a height of 3.2 metres. Their respective velocities just before touching the ground will be: (Assume acceleration due to gravity g=10m/s^2)

• A. 8 m/s and 4 m/s
• B. 3.2 m/s for both
• C. 4 m/s and 8 m/s
• D. 8 m/s for both

Answer 1

Answer:

D. 8 m/s for both

• Objects dropped from a certain height are in a state of free fall if the only force acting on them is gravity. Air resistance is often neglected in these idealized scenarios. • In free fall, all objects, regardless of their mass, accelerate downwards at the same rate due to gravity.
