Solution
Correct Answer:
25 J
- Application of Principle: The work done is equal to the final kinetic energy since the particle starts from rest.
- Kinetic Energy Formula: K=21mv2.
- Identify Variables:
- Mass m=0.5 kg.
- Velocity v=10 m/s.
- Calculation:
- W=21×0.5×102=0.25×100.
- Result: W=25 Joules.
