On a cricket field, the batsman is at the origin of coordinates and a fielder stands in position given as \( (46 \hat{i}+28 \hat{j}) \mathrm{m} \). The batsman hits the ball so that it rolls along the ground with constant velocity given by \( (7.5 \hat{i}+10 \hat{j}) \mathrm{m} / \mathrm{s} \). The fielder can run with a speed of \( 5 \mathrm{~m} / \mathrm{s} \). If the starts to run immediately the ball is hit, what is the shortest time in which he could intercept the ball.
