Many birds drop clams or other shell fish in order to break the shell and get the food inside. Suppose a crow drops a shell from a height of 5.2m. How long does it take to reach the ground?

Answer 1

The rate of gravity acceleration is 9.81 m/s/s

5.2m * (1second/9.81m)= .53 sec= .009 min= 1.47e^-4 hours= 6.14e^-6 days
