In order to open the clam it catches, a seagull will drop the clam repeatedly onto a hard surface from high in the air until the shell cracks. if a seagull flies to a height of 23.1 m, how long will the clam take to fall? the acceleration of gravity is 9.8 m/s 2 . answer in units of sec.

2.2 s

Explanation:

Hi!

Let's consider the origin of the coordinate system at the ground, and consider that the clam starts with zero velocity, the equation of motion of the clam is given by

We are looking for a time t for which x(t) = 0

Solving for t:

Rounding at the first decimal:

t = 2.2 s
