A quick distance/time question.

• skg94
In summary, the problem involves finding the vertical height of an aircraft using a radar pulse that is projected at an angle of elevation of 22.0 degrees and takes 1.28*10^-4s to make a round trip. The height of the radar transmitter/receiver can be ignored. One possible method to solve this problem is by using the equation d=vt to find the hypotenuse, and then using sin feta to find the vertical height. Another approach is to use the given time to calculate the total distance traveled and then divide it by 2.

Homework Statement

A radar pulse projected at an angle of elevation of 22.0 degrees is reflected from an aircraft and returned. If the pulse takes 1.28*10^-4s to make the round trip, then the vertical height of the aircraft is? (Height of radar transmitter/receiver can be ignored)

The Attempt at a Solution

I know how to do it, just use d=vt to find the hyp and then use sin feta to find vertical height.

But for time do i use 1.28*10^-4s? or use half of that since that time is the round trip?

I woud do it that way, you have the right thinking... you can also use that time and get the total distance and divide that by 2...

I thought feta was a type of Greek cheese.

1. How do you calculate distance given time and speed?

To calculate distance, use the formula: distance = speed x time. This means that if you know the speed at which an object is traveling and the time it takes to travel, you can multiply those two values to find the distance it has traveled.

2. What is the formula for calculating time given distance and speed?

The formula for calculating time is: time = distance / speed. This means that if you know the distance an object has traveled and its speed, you can divide the distance by the speed to find the time it took to travel that distance.

3. How does an increase in speed affect the distance traveled?

An increase in speed will result in a greater distance traveled in the same amount of time. This is because the faster an object moves, the more ground it covers in a given time period.

4. Can distance and time be used to calculate speed?

Yes, speed can be calculated by dividing distance by time. The formula for speed is: speed = distance / time.

5. How can you convert units of distance and time when calculating speed?

To convert units of distance and time, use conversion factors. For example, to convert from miles per hour to meters per second, multiply the miles per hour value by 0.44704. You can find conversion factors for different units of distance and time online or in a physics reference book.
