Find the height of the frog at the instant the stick hits the ground:

1.56 m

Explanation:

The center of mass is initially at a height of 1.80 m.  After 0.42 seconds, it falls to a height of:

y = y₀ + v₀ t + ½ at²

y = 1.80 + (0)(0.42) + ½ (-9.8)(0.42)²

y = 0.936

Using definition of center of gravity:

(7.05 + 4.70) (0.936) = (7.05) h + (4.70) (0)

h = 1.56

The frog's height is 1.56 meters (remember to round to the same number of significant figures as the data provided).

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
