How do you find the wave speed with the wavelength and amplitude?
Not enough information. You can use the equation speed = frequency x wavelength, but in this case, you don't have enough data to calculate the speed.
How is distance and time related to the speed of an object?
In the case of constant speed: distance = speed x time. Or, Total distance = Average speed * Total Time
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
If a train goes 95 km per hour for 250 km and returns at 65km per hour for 250 km what is the average velocity?
You can't calculate the average of 95 and 65 in this case - the answer will be slightly off. Instead, calculate the time the train took to go one way, and the time it took to go back. Then divide the total distance by the total time. This will give you the average SPEED. (Average VELOCITY will be zero, since the train gets back to its starting point.)
How long will it take to drive 286 miles at an average speed of 52 miles per hour?
The basic formula is: distance = speed x time In this case, you have to divide the distance by the speed.
When is speed equal to the magnitude of velocity?
That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.
How do you find mean kinetic energy when given only mass and horizontal distance traveled?
You don't have enough information in this case. Kinetic energy depends on mass and speed. Speed can be calculated as distance / time - and no time is given, nor is there any other information that allows you to calculate the time. Note that even if time is given, you can calculate the average (mean) speed, but that will only give you a rough idea of the mean kinetic energy. In this problem, if the speed changes a lot, the average kinetic energy (averaged over time) will be greater than in the case of a constant speed. This is because kinetic energy is proportional to the square of the speed.
How do you find the wave speed with the wavelength and amplitude?
Not enough information. You can use the equation speed = frequency x wavelength, but in this case, you don't have enough data to calculate the speed.
How can you calculate the distance using the formula?
There are several formulae for different cases. For the case of a constant speed, use the formula: distance = speed x time.
How is distance and time related to the speed of an object?
In the case of constant speed: distance = speed x time. Or, Total distance = Average speed * Total Time
What is the average speed between 0 and 2 seconds?
To find the average speed between time=0 and time=2, divide the distance traveled by the time (in this case 2 seconds).
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
If a train goes 95 km per hour for 250 km and returns at 65km per hour for 250 km what is the average velocity?
You can't calculate the average of 95 and 65 in this case - the answer will be slightly off. Instead, calculate the time the train took to go one way, and the time it took to go back. Then divide the total distance by the total time. This will give you the average SPEED. (Average VELOCITY will be zero, since the train gets back to its starting point.)
How can you calculate the acceleration of an object moving in a straight line by?
It really depends what information you are given. In the simplest case, you use the definition of acceleration as delta(speed) / time. That is, you divide the change (delta) in speed, and divide by how long it takes for this change in speed. This gives you the average acceleration over the given time. If you assume a constant acceleration, it is also the instantaneous acceleration at any moment.
Which describes the average velocity of an ant traveling at a constant speed in a straight line on the kitchen counter?
The slope of the ant's displacement vs. time graph The total displacement divided by the time.
What is its average speed during this 11 s interval?
To get average speed, just divide distance by time. In this case, you divide whatever distance an object moves during the 11 seconds, by the 11 seconds.
How long will it take to drive 286 miles at an average speed of 52 miles per hour?
The basic formula is: distance = speed x time In this case, you have to divide the distance by the speed.
