Answer:
a) 
b) 
Step-by-step explanation:
a) We have the following equation:
(1)
Where 
is the time is seconds, 
is the distance in meters and 
is the acceleration due gravity
If we divide numerator and denominator inside the square root by 2:
We will have:
Hence:
b) Using the same equation (1) with thw following data:
We will have the reaction time:
Answer:
8 1/2
Step-by-step explanation:
2 1/2 + 2 1/3 + 3 2/3
= 2 3/6 + 2 2/6 + 3 4/6
= 7 9/6
= 8 3/6
= 8 1/2
Good morning
Answer:
B: (1, 5)
Step-by-step explanation:
