Answer:
3.94
Step-by-step explanation:
1.97 times 2 equals 3.94
Some periodic motions, also known as armonic motions, with which much of us are familiar with are:
- The motion of the swinger when a kid is balancing forward and backward
- The motion of a pendulum
- The motion of the needles of a watch.
- The motion of a satelite around a planet.
- The spinning of the wheel of a stationary bycicle.
- A rocking chair
All the motions in which the object passes once and other times through the same point are periodic motions.
Both scientists and businesses are interested in tracking periodic motions using equations because they appear in many situations in nature and in daily life. The cycles are examples of periodic motion. By tracking this type of motion you can make models that permit you to explain the phenomena and predict cycles. This is predict facts that repeast with a certain period.
6m + 15m+ 20= 75
6m+ 15m= 75- 20
21m= 55
m= 55/21
m= 2.61
