The area of the square is side^2
1536=s^2
Square root of 1536=39.19
Side length =39.19
Integers are like -4,-3,-2,-1,0,1,2,3,4,5 etc
absolute value tells you how far the number is from 0
so example: |-5|=5=|5|
2 different integers can have the same absolute value
as long as they are negative of each other
like x and -x
Answer:
Time at which the hammer reaches the ground is 2.3 seconds.
Step-by-step explanation:
We are given the formula as,
.
It is known that, when height i.e.
meter, then velocity
m/sec.
So, we get the formula as,
.
Now, when the hammer hits the ground, the height
meter.
Thus, we have,

⇒ 
⇒ 
⇒ 
i.e. t= ±2.3 sec
Since, time cannot be negative.
So, t= 2.3 sec
Hence, the time at which the hammer reaches the ground is 2.3 seconds.
