When a radar gun says the pitch is 90 miles per hour at what point in the ball's travel to home plate is the radar gun measuring the velocity?
== The measurement is made at the point where the ball is when
the trigger is squeezed and the contacts close to activate the
unit. The gun responds in a "split second" by sending out a pulse,
catching the return, and then comparing the two to discover the
difference (the Doppler shift). It is so fast that the ball doesn't
travel very far in the time it takes the unit to respond and
resolve the speed. == It depends upon the radar gun. Some radar
guns lock the speed at the instant the operator depresses the
trigger. Other radar guns (such as the Bushnell® VelocityTM radar
gun) include a feature that locks in the fastest speed that
occurred during the entire time the trigger was
If the question refers to the time taken for a journey then this obviously depends on the speed of travel. Velocity (or speed) = Distance ÷ Time. So Time = Distance ÷ Velocity. Example : If you were travelling at 40 mph (miles per hour) then the time taken is 47/40 = 1.175 of an hour which equals 1 hour and 10½ minutes.
v=^x/^t Velocity is measured by distance traveled divided by time taken to travel. Or more simply explained: Velocity = Displacement ÷ Time So, say your car is driving on a road where as you pass by a road sign which says 60 mph. That is your current velocity. Your car's velocity = 60m÷h = 60mph to work back you could say that you have traveled 60 miles in one hour. Your car's velocity = 60…
A car is traveling at a constant velocity.After two hours the car has traveled 90 miles. After five hours the car has traveled 225 miles.How far will the car have traveled after seven hours?
Speed and velocity are different. Speed is how fast something's moving. Velocity is speed combined with the direction the thing is moving. Speed is calculated by dividing the distance traveled by the time it took to travel this distance. For example, if you drove 100 miles in two hours the speed would be 100 divided by 2 or 50 miles per hour.
Velocity is measured as a unit of distance over time as in miles/hour (miles per hour). feet/second, kilometers/hour. It is the same as a measurement of speed except that there is also a direction component as in north or southwest. If you change the direction travel but maintain the same speed, it is still a change in velocity even though it is not a change in speed..
Since distance (D) equals velocity (V) xtime (T) (D = V x T), then time equals distance divided by velocity or T = D/V. For example, going 20 miles per hour for 2 hours will move a distance of 40 miles. Looking at it the other way, 40 miles divided by 20 miles per hour will equal 2 hours of travel time. PJ
You first need to acquire more data. Since Velocity is equal to Displacement traveled divided by Time (v=s/t) if you know the distance traveled by the object and the time it has taken the velocity can be computed. watch those units though. if your measuring in meters and timing in seconds your velocity will be in meters/second so this needs to be converted if you are looking for miles or kilometers/hour
Speed is the rate at which something moves, and can be calculated by the equation: speed = distance / time. Speed does not have a direction associated with it. So if you are in a car and travel 60 miles in 2 hours, your average speed would be 30 miles per hour. Velocity is very similar to speed, but it does have a direction associated with it. That is the only difference.
What is the distance traveled by an object divided by the time it takes to travel that distance called?
The distance traveled by an object divided by the time it takes to travel that distance is called the average speed, r, if you are also considering its direction, its average velocity. Velocity = distance in one direction/time Speed = distance/time For example: A car that travels 60 miles in a time of 2 hours has a speed of 30 miles per hour.
that changing slope on a distance-time graph is changing velocity. Think of how distance per unit time is velocity (miles per hour or meters per second). If that is constant, then the slope of the line should be constant - you will travel the same number of miles or meters for each successive hour or second. If the velocity changes, then the slope of the line will change.
Depends on how fast you're going..... Velocity=distance/time. i.e. if your distance = 9 miles, and your velocity=50 mph, then you'll get a time=9/50=.18 hours= 10.8 minutes. Hopefully this answers your question. If you want to find a more accurate answer with a variable speed however, you'll need to use some simple calculus. A commercial airliner takes 1 minute to travel 9 miles going 540 mph.
