JEE Mains · Physics · STD 11 - 5. work,energy,power and collision
A particle moves in one dimension from rest under the influence of a force that varies with the distance traveled by the particle as shown in the figure. The kinetic energy of the particle after it has traveled \(3\, m\) is ................ \(\mathrm{J}\)
- A \(2.5\)
- B \(4\)
- C \(5\)
- D \(6.5\)
Answer & Solution
Correct Answer
(D) \(6.5\)
Step-by-step Solution
Detailed explanation
According to work energy theorem. Work done by force on the particle \(= Change\, in\, KE\) \(work\, done = Area \,under F-x \,graph =\) \(\int {F.dx\, = } \)…
