Challenge Problems (Problem 109)

A drone is being directed across a frictionless ice-covered lake. The mass of the drone is 1.50 kg, and its velocity is $3.00\hat{i}\text{m}\text{/}\text{s}$. After 10.0 s, the velocity is $9.00\hat{i}+4.00\hat{j}\text{m}\text{/}\text{s}$. 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. Select the answer to part (b).
