A diffuse, spherical object of diameter and temperature 9 mm and 600 K, respectively, has an emissivity of 0.95. Two very sensitive radiation detectors each with an aperture area of 300 x 10-6 m2, detect the object as it passes over at high velocity from left to right as shown in the schematic. The detectors capture hemispherical irradiation and are equipped with filters characterized by ?? = 0.9 for ?? 2.5?m. At time t1 = 0, detectors A and B indicate irradiations of GA,1 = 5.060mW/m2 and GB.1 = 5.000mW/m2, respectively. At time t2 = 4 ms. detectors A and B indicate irradiations of GA,2 = 5.010mW/m2 and GB,2 Z = 5.050mW/m2, respectively. The environment is at 300 K. Determine the velocity components of the particle, vx and vy. Determine when and where the particle will strike a horizontal plane located at y = 0.
