Question

A variable force, given by the 2-dimensional vector
F = (4xî + 3yj), acts on a particle. The force is
in newton and x is in metre. What is the change
in the kinetic energy of the particle as it moves
from the point with coordinates (3,2) to (0,3) ?
(The coordinates are in meters)
(1) -1 J
(2) Zero
(4) +7 J
(3) +1J​

Answer 1

Answer:

i think it may be 7 J or may be zero.
