A photosensitive material is at 9 m to the left of the origin and the source of light is at 7 m to the right of the origin along x-axis. The photosensitive material and the source of light start from rest and move, respectively, with 8iˆms^−1 and 4iˆms^−1. The ratio of intensities at t=0 to t=3s as received by the photosensitive material is
