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).

this means that the temperature of both substances will be equal

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
