A car travels 100 miles east in 2 hours and 30 miles north in one hour. What is the average speed of the car?
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
What is the velocity of a car that traveled a total amount of 75 kilometers north in 1.5 hours?
50km/hour North.
Is speed equal to velocity?
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
What is 20 miles per hour north an example of?
A velocity vector includes both speed and direction.
Which is 20 miles per hour north an example of?
A vector. This is because the quantity given has a magnitude (20mph) and a direction (North). It is also an example of a velocity.
Find the velocity of a truck that travels 75 miles north in 2.5 hours?
Speed = Distance divided by Time. So, speed = 75 miles divided by 2.5 hours = 75 / 2.5 = 30 miles per hour. Velocity is speed and direction, so the velocity is 30 mph Northbound.
What is the velocity of an car that travels 50 miles north turns around and travels 50 miles south in 5 hours Question 6 options 0 2 mph south 5 mph south 25 mph north?
The car's net displacement is 0 miles (north 50 miles - south 50 miles). Since the total time taken is 5 hours, the velocity is 0 mph because velocity is displacement divided by time, resulting in 0 mph.
A car travels 100 miles east in 2 hours and 30 miles north in one hour. What is the average speed of the car?
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
What is the velocity of a car that travels 260 miles in 4 hours driving to the northeast?
The velocity of the car is 65 miles per hour. This is calculated by dividing the distance traveled (260 miles) by the time taken (4 hours). Since direction is not specified in the calculation of velocity, the northeast direction does not affect the final answer.
What is a example of a value for velocity?
30 miles per hour north
What is the velocity of a car that traveled a total of 100kilometers North in 2 hours?
The average velocity during that period of time is 100 kilometers per 2 hours north. It may also be stated as 50 kilometers per hour north.
Is six miles per hour per second north an example of velocity?
We're not completely sure what you mean by "per hour per second". Going just by what we see in the question, it's an acceleration, not a velocity. "Six miles per hour north" would be a velocity.
What is the velocity of a car that traveled a total amount of 75 kilometers north in 1.5 hours?
50km/hour North.
What is the difference between speed and velocity is that velocity?
Velocity is speed and its direction. "30 miles per hour" is a speed. "30 miles per hour north" is a velocity". "30 miles per hour north" and "30 miles per hour south" are identical speeds but different velocities.
What is speed and how is speed different from velocity?
Velocity is speed plus direction. If you say you are traveling at 54 miles per hour, you are giving your speed. If you say you are going north at 54 miles per hour, you are giving your velocity.
A powerful storm attacks the North Carolina coast with winds blowing at 89 miles per hour What is the velocity of these winds?
The velocity of the winds blowing at 89 miles per hour during a storm on the North Carolina coast is 89 miles per hour.
The difference between speed and velocity is that velocity include?
Speed is a scalar and velocity is a vector. A scalar only has magnitude while a vector has magnitude and direction. Example: If you are traveling north at 65 miles an hour your speed is 65 miles an hour, your velocity is 65 miles an hour north. It gets a little more complicated. Speed = distance (a scalar)/time Velocity = Displacement (vector)/time Example: If you run 5 miles in an hour left and then 5 miles in a hour right your speed is 10 miles/2 hours = 5 miles an hour. However, since you end up in the same exact location as where you started your displacement is zero making your velocity zero as well. Think of it this way; since velocity is a vector it requires a direction if i ended up exactly where I started I have no direction, thus velocity must be zero. One more example to clarify: If you ran 6 miles right and 4 miles left in 2 hours, your speed will be 5 miles an hour (10/2=5) your velocity would be 1 mile an hour to the right, since displacement is 2 miles to the right (6 to right - 4 to left = 2 to right) and the time is 2 hours displacement/time = velocity; 2 to the right/2 = 1 mile to the right per hour.
