A firecracker breaks up into two pieces, one has a mass of 200 g and flies off along the x-axis with a speed of 82.0 m/s and the second has a mass of 300 g and flies off along the y-axis with a speed of 45.0 m/s
What is the total momentum of the two pieces? A)
361 kg?m/s at 56.3° from the x-axis
B)
93.5 kg?m/s at 28.8° from the x-axis
C)
21.2 kg?m/s at 39.5° from the x-axis
D)
361 kg?m/s at 0.983° from the x-axis
E)
21.2 kg?m/s at 56.3° from the x-axis
C

In principle, the Drake equation should enable us to calculate the exact number of intelligent civilizations capable of interstellar communication in our galaxy right now. However, currently this is not feasible because
A) we do not have exact numbers for any of the factors in the equation B) it is impossible for us to ever know the values of any of the factors C) we have exact numbers for the first three factors, but not the last factor D) we have an exact number for the first factor, but not for any of the other factors
