An eagle is coasting at 1.2 m/s when it sees a prey 30.7m away. If the eagle's acceleration is 2.7 m/s2, how fast was the eagle going when it reached the prey?

The first-order reaction a→2b+c has rate constant 0.538 s−1. if the initial concentration of a is 0.867 mol l−1, what is the half-life of the reaction in seconds? remember to use correct significant figures in your answer (round your answer to the nearest hundredth). do not include units in your response.
