Final answer:
The time it takes for a pendulum with a 1.5 m string to complete one full swing is calculated using the period formula T = 2π√(L/g) and is approximately 3.93 seconds.
Step-by-step explanation:
To calculate the time it takes for a pendulum with string length 1.5 m to complete one full swing, we can use the formula for the period (T) of a simple pendulum, which is T = 2π√(L/g), where L is the length of the string and g is the acceleration due to gravity (approximately 9.81 m/s2).
Plugging in the values, we get:
T = 2π√(1.5/9.81)
T ≈ 2π√(0.153)
T ≈ 2π√(0.391)
T ≈ 2π(0.625)
T ≈ 3.927
Therefore, the time for the pendulum to complete one full swing is approximately 3.93 seconds.
