Question 877894: Please help me answer this question using this equation:
+T=+2%283.142%29+sqrt+%28L%2Fg%29+
The time T (in seconds) needed for a pendulm to make a complete swing is given by this formula above where L is the length of the pendulm and g= 980 com/sec^2. Find the time needed to complete a swing if the length is 50 cm.

You can put this solution on YOUR website!
In this case, L = 50 and g = 980. Plug them into the equation and evaluate with a calculator


+T=+2%283.142%29+sqrt+%28L%2Fg%29+
+T=+2%283.142%29+sqrt+%2850%2F980%29+
+T=+1.4194109+


So it takes approximately 1.4194109 seconds.
