The Blitz-contest of IOM-2020
Условие
A penguin is jumping into the water from the uniform springboard, which rotates freely around the joint on the left and is firmly connected to the spring on the right. The length of the bridge plate is 2.0 m, the weight is 12 kg, the spring stiffness is 1300 N/m. The weight of the spring is negligible. When the penguin jumps, the bridge begins to oscillate with a small amplitude. What is the period of this oscillation? The board is solid, does not bend.
The answer should be given in the SI units unless otherwise stated. If the numerical result turns out to be an integer, it should be given as the answer. Otherwise round the result to the first decimal.
