Average speed = Total Distance/Total Time = (15+25)/2 = 40/2 = 20 miles per hour.
Velocity (due North) = Total NET distance North/Total Time = (15-25)/2 = -10/2
= -5 miles per hour
or, velocity due South = 5 miles per hour.
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
50km/hour North.
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.
A velocity vector includes both speed and direction.
A vector. This is because the quantity given has a magnitude (20mph) and a direction (North). It is also an example of a velocity.
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.
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.
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
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.
30 miles per hour north
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.
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.
50km/hour North.
Speed is a scalar quantity that measures the rate of motion, while velocity is a vector quantity that includes both speed and direction. Speed only tells you how fast an object is moving, but velocity tells you how fast it's moving and in which direction.
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.
The velocity of the winds blowing at 89 miles per hour during a storm on the North Carolina coast is 89 miles per hour.
Velocity includes both the speed of an object and its direction of motion, while speed only refers to how fast an object is moving without considering the direction. Velocity is a vector quantity, meaning it has both magnitude and direction, whereas speed is a scalar quantity with magnitude only.
