NEET Physics Work-Energy Theorem MCQ Question
A raindrop of mass 1.00 g falls from a height of 1.00 km and hits the ground with a speed of 50.0 m/s. If the gravitational acceleration is 10 m/s², what is the work done by the resistive force on the raindrop?
-8.75 J
0 J
25 J
10.0 J
Correct Answer
Detailed Explanation
The work-energy theorem states that the change in kinetic energy is equal to the work done by all forces. Given the gravitational work is 10 J and the kinetic energy change is 1.25 J, work done by resistive force is -8.75 J.
