Answer:
1.72 m
Explanation:
Potential energy = mgh, where m is mass, g is acceleration due to gravity (9.8), and h is height
76 = (3.5)(9.8)h
76=44.1h
h=1.72335600907 ≈1.72 m
The distance traveled by pendulum, in one back-and-forth swing is 75.75 inches.
The period of pendulum can be calculated by

Where,
- period
- length = 12 inches
- gravitational acceleration = 
Put the values,

Now, the angular displacement of the pendulum can be calculated by,

Where,
- amplitude
- angle = 
- angular displacement =
= 2.866 m
Put the values and calculate for
,

Therefore, the distance traveled by pendulum, in one back-and-forth swing is 75.75 inches.
