Answer:
6.1 s Â
Step-by-step explanation:
h = -16t² + 600
When the sack reaches the ground, h = 0.
  0 = -16t² + 600
16t² = 600
 t² = 600/16
 t² = 37.5
  t = 6.1 s
It will take 6.1 s for the sack to reach the ground.
It  takes  6.1 s for the sack to reach the ground.
We have given that the expression
h = -16t² + 600
What is the height when sack reaches the ground?
at ground height is 0
Therefore,When the sack reaches the ground, h = 0.
[tex]0 = -16t^2 + 60016t^2 = 600 t^2 = 600/16 t^2 = 37.5 t = 6.1 s[/tex]
Therefore ,It will take 6.1 s for the sack to reach the ground.
