A boat crosses a river at a constant engine speed of 8.0 cm/s under the influence of a constant perpendicular current acceleration of 0.060 m/s².How far off a straight course does it drift in 2.3 min? A)570 m B)0.16 m C)4.1 m D)1700 m

The boat's velocity due to the current is:$$v_c=at=(0.060	ext{ m/s}^2)(2.3	ext{ min})(60	ext{ s/min})=8.28	ext{ m/s}$$The boat's displacement due to the current is:$$d_c=v_ct=(8.28	ext{ m/s})(2.3	ext{ min})(60	ext{ s/min})=570	ext{ m}$$
