Speedy, the super-swift squid, swims sideways at 5.3 m/s. if he suddenly uses his ink jet to accelerate at 15 m/s/s for 2.1 s, what is his final speed in miles per hour? round to no decimal places.

Chameleons catch insects with their tongues, which they can rapidly extend to great lengths. in a typical strike, the chameleon's tongue accelerates at a remarkable 220 m/s2 for 20 ms, then travels at constant speed for another 30 ms.
