Crow on roof Part D | Problem A 0.680 kg crow slides down an inclined roof, as shown in the gure. The roof makes an angle of 300 with respect to the horizontal. There is negligible friction between the roof and the crow. Use 3 = 9.80 m/sz. Using the acceleration found part (c), what is the magnitude of the acceleration of the crow? 0 m/s2 3.33 m/52 9.80 m/52 4.90 m/s2 8.49 m/s2 4.24 m/s2 2.45 m/s2
