## Linear Motion Example Problems

Linear motion is a fundamental concept in physics that describes the movement of an object along a straight path. It is a type of motion that occurs when an object moves in one direction, without deviating from its path. In this section, we will explore some example problems that involve the calculation of distance, speed, and time in linear motion scenarios.

### Calculation of Distance, Speed, and Time

When dealing with linear motion, it is often necessary to calculate various parameters such as distance, speed, and time. These calculations can help us understand the motion of an object and make predictions about its future behavior. Let’s take a look at a few example problems to illustrate this concept.

#### Example 1: Calculating Distance

Suppose a car travels along a straight road for 2 hours at a constant speed of 60 miles per hour. To calculate the distance traveled by the car, we can use the formula:

`Distance = Speed × Time`

In this case, the speed of the car is 60 miles per hour, and the time is 2 hours. Plugging these values into the formula, we get:

`Distance = 60 miles/hour × 2 hours = 120 miles`

Therefore, the car travels a distance of 120 miles.

#### Example 2: Calculating Speed

Let’s consider a different scenario. Suppose a person walks a distance of 500 meters in 10 minutes. To calculate the speed at which the person is walking, we can use the formula:

`Speed = Distance ÷ Time`

In this case, the distance is 500 meters, and the time is 10 minutes (which we need to convert to hours). Converting 10 minutes to hours, we get:

`Time = 10 minutes ÷ 60 minutes/hour = 0.167 hours`

Now, plugging the values into the formula, we have:

`Speed = 500 meters ÷ 0.167 hours ≈ 2994 meters/hour`

Therefore, the person is walking at a speed of approximately 2994 meters per hour.

#### Example 3: Calculating Time

Let’s consider a scenario where a train travels a distance of 300 kilometers at a speed of 100 kilometers per hour. To calculate the time taken by the train to cover this distance, we can rearrange the formula for speed:

`Time = Distance ÷ Speed`

In this case, the distance is 300 kilometers, and the speed is 100 kilometers per hour. Plugging these values into the formula, we get:

`Time = 300 kilometers ÷ 100 kilometers/hour = 3 hours`

Therefore, the train takes 3 hours to cover a distance of 300 kilometers.

In conclusion, calculating distance, speed, and time is essential in understanding linear motion problems. By applying the appropriate formulas, we can determine these parameters and gain insights into the motion of objects. These calculations are not only useful in physics but also in various real-life scenarios, such as calculating travel distances, speeds, and times.
