Answer:
1.57 s
Explanation:
Since the motion of the hammer is a uniformly accelerated motion, the distance covered by the hammer in a time t is
Where, in this case
S = 2.0 m is the distance covered
a = 1.62 m/s^2 is the acceleration due to gravity
t is the time taken
Re-arranging the equation, we can find the time the hammer takes:
