Chapter 5, Problem 109CP

A drone is being directed across a frictionless ice- covered lake. The mass of the drone is 1.50 kg, and its velocity is $3.00\text{<mover accent="true"> <mi> i </mi> <mo> ^ </mo> </mover> m/s}$ . After 10.0 s, the velocity is $9.00\text{<mover accent="true"> <mi> i </mi> <mo> ^ </mo> </mover>}+4.00\text{<mover accent="true"> <mi> j </mi> <mo> ^ </mo> </mover> m/s}$ . If a constant force in the horizontal direction is causing this change in motion, find (a) the components of the force and (b) the magnitude of the force.
