Helga [31]

Answer:

The period when its more than halfway

= 2 < t  ≤ 2.83 seconds   ( to nearest hundredth).

Step-by-step explanation:

When is is halfway down the ramp d = 3920/2 = 1960 cm, so:

1960 = 490 t^2

t^2 = 1960/490 = 4

t = 2 seconds.

When it reaches the bottom d = 3920 :

t^2 = 3920/490 =  8

t = 2.83 seconds.
