PhysicsW.E.P.Work kinetic energy theoremEasy2 minQB

PhysicsEasysingle choice

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:

Options:

Answer:

Solution:

Change in K.E. $=$ Work done $=$ Area
Area $= (3 \times 2) + (\frac{1}{2} \times 1 \times 1) = 6.5$
$∴$ Change in kinetic energy $= 6.5 J$
