Question

A body of mass 5 kg, is at a height of 10m from the ground. Assuming, g = 10 ms–2

, answer the following

questions. Ignore friction due to air. [4]

i) The potential energy of the body is

1. 500N 2. 500J 3. 50N 4. 0.5J

ii) If the body is dropped, then the maximum kinetic energy gained by the body is

1. 500N 2. 500J 3. 50N 4. 0.5J

iii) While falling, the potential energy of the body, mid-way through the fall is

1. 250N 2. 250J 3. 25N 4. 0.25J

iv) The sum of potential energy and kinetic energy of the body, at any point, while falling is

1. 500N 2. 500J 3. 50N 4. 0.5J​
