David drops a ball from a bridge at an initial height of 100 meters.
dedylja [7]
The general formula is:
y = y_{o} + v_{o}t -  \frac{1*g*t^{2} }{2} -- (A)

Where g = 9.8 m/s/s
v_{o} = 0
y_{o} = 100

a)
Time=t=3s.
Plug-in the values in (A)
y = 100 -(1/2*9.8*3*3)
y = 100-44.1 = 55.9m

Height of the ball exactly after 3 seconds = 55.9m.

b)
At ground, y=0; Plug-in values in (A):
A=> 0 = 100 - (1/2* 9.8 * [tex]t_{2}[/text])
Therefore t = + 4.52 s and - 4.52 seconds.

As t cannot be negative, therefore:
Time when ball hits the ground = 4.52s
