A particle moves in the plane in polar coordinates (r,θ), where the radial speed is constant dtdr=5 m/s and the angular speed is constant dtdθ=0.5 rad/s. At t=0 the particle is at the point (4,0), which corresponds to Cartesian coordinates (4,0). Which of the following is the best approximation of the particle’s Cartesian position at t=2 seconds?
a) ⟨14,1⟩
b) ⟨11.8,7.6⟩
c) ⟨7.6,11.8⟩
d) ⟨12.3,6.7⟩
