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.
Is this multiple choice if so what are the options <span />
