Additional Problems (Problem 85)

Consider a particle on which several forces act, one of which is known to be constant in time: ${\vec{F}}_1=(3\text{N})\hat{i}+(4\text{N})\hat{j}.$ As a result, the particle moves along the x-axis from $x=0$ to $x=5\text{m}$ in some time interval. What is the work done by ${\vec{F}}_1$ ?
