Problem

A particle experiences a variable force

\vec{F} = (4x\hat{i} + 3y^2\hat{j})

in a horizontal

x

y

plane. Assume distance in meters and force is newton. If the particle moves from point (1, 2) to point (2, 3) in the

x

y

plane, then Kinetic Energy changes by : A 25 J B 50 J C 12.5 J D 0 J
