A particle moves in a plane in which and are perpendicular unit vectors. A force, acts on the particle. The particle moves from the origin to the point with position vector m. Find the work done by the force.
A force N is acting on a particle whose position vector as a function of time is given by m. Calculate the work done by the force between and seconds.
An object moves 10 m in the direction of . There are two forces acting on this object: N and N. Find the total work done on the object by the two forces.
Hint: You can take the work done by the resultant of the two forces or you can add the work done by each force.
