Velocity final = vi + at = 49 m/s
displacement = vi * t + ½2at² = 122.5 m
vi = 0
a ≈ 9.8
t = 5

What is the height of a tower if a rock dropped from it hits the ground after falling for 2 seconds?
19.6 meters / 64.4 ft
How far does a rock fall in 9 seconds?
depends on the mass of the stone, the shape of the stone, and the height dropped from. sorry dude.

David drops a ball from a bridge at an initial height of 70 meters what is the height of the ball to the nearest tenth of a meter exactly 2 seconds after he releases the ball?
Distance of fall in T seconds = 1/2 g T2Distance of fall in 2 seconds = (1/2) (9.8) (2)2 = (4.9 x 4) = 19.6 metersHeight of this particular ball after 2 seconds = (70 - 19.6) = 50.4 meters
How do you find the frequency if you only have seconds and height of a wave?
Assuming that seconds refers to the period, the frequency is the reciprocal (1 / period in seconds). The height of the wave is irrelevant in this case.
A marble is dropped from a bridge and strikes the water in 5 seconds Calculate the speed with which it strikes and the height of the bridge?
Neglecting air resistance . . .The acceleration of gravity is 9.8 meters (32.2 feet) per second2.After 5 seconds the marble's downward speed is (9.8 x 5) = 49 meters (160.8-ft) per second.Its average speed during the fall is (49/2) = 24.5 meters (80.4-ft) per second.The distance it falls is (24.5 x 5) = 122.5 meters (402-ft).

How does the height a boucny ball is dropped from effect the height it bounces to?
The higher the height the ball is dropped from, the higher the height it will bounce to.
How do you find the height of the tower given only 8 seconds stone is dropped?
distance = speed x time so the distance is just the speed of the stone x 8 seconds

Is height a factor in lighting strikes?
There are three factors in lightning strikes. These are height, isolation, and shape. Higher structures will be more susceptible to lightning strikes than shorter ones.
