A block of mass 2 kg is free to move along the x-axis. It is at rest and from t = 0 onwards it is subjected to a time-dependent force F(t) in the x direction. The force F(t) varies with t as shown in the figure. The kinetic energy of the block after 4.5 seconds is

- 4.50 J
- 7.50 J
- 5.06 J
- 14.06 J
Answer
(D) 14.06 J
