A pendulum with a length of 1.25m has a period of 2.2s. What is the value of g?
I am not sure which equation I would use to solve this problem.
Never mind, I have solved it. :)
To find the value of g, we can use the formula for the period of a pendulum. The formula is given as:
T = 2π√(L/g)
where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.
In this case, we know the length of the pendulum (L = 1.25m) and the period (T = 2.2s). We can rearrange the formula to solve for g:
T = 2π√(L/g)
Squaring both sides of the equation, we get:
T^2 = 4π^2(L/g)
Now, we can solve for g:
g = 4π^2(L/T^2)
Plugging in the values we have, we get:
g = 4π^2(1.25 / 2.2^2)
Evaluating this expression, we can calculate the value of g.
