HockeyPuck 3 of 15 Review | Constants A rocket-powered hockey puck moves on a horizontal frictionless table. The figure (Figure 1)at the top of the next column shows graphs of v and vy the x- and y- Part B components of the puck's velocity. The puck starts at the origin. How far from the origin is the puck at t 5 s? The distance is the magnitude of the position vector at 5s. Since the position vector r(t) is given by x(t) in i-hat direction and y(t) in j-hat direction, the magnitude of the position vector is sqrt( x(t)^2+y(t)^2)=sqrt( x(5)^2+y(5)^2) Figure 1 of 1 Express your answer using two significant figures.
