Physics
Sometimes the curiosity factor at the scene of a car accident is so great that it produces
secondary accidents as a result, while people watch to see what is going on. If an 800.-kg
sports car slows to 13.0 m/s to check out an accident scene and the 1200.-kg pick-up
truck behind him continues traveling at 25.0 m/s, with what velocity will the two move if
they lock bumpers after arear-end collision?

Ответ:
increased by 9 times
Explanation:
As the period of a simple pendulum is defined as the following formula
where L is the length of the pendulum and g is the constant gravitational acceleration. Since L is under a square root, if you want to triple the period of vibration, L must be increased by 9 times so that
