Answer:
t is approximately 10.41 seconds
Step-by-step explanation:
s = 16t^2
1734 = 16t^2
divide by 16
1734/16 = 16t^2/16
1734/16 = t^2
take the square root of each side
sqrt(1734/16) = sqrt(t^2)
we only take the positive square root because time must be positive
sqrt(1734/16) = t
t is approximately 10.41 seconds
