A train starting from rest attains a velocity of 72Km hr in 5 minutes. Assuming that the acceleration is uniform what is the distance travel by train while attained the velocity?
As the acceleration is uniform, the train has an average speed that is half the difference between the start and final velocities, which in this case is half the final velocity. 1 hr = 60 min 1 km/h = 1 km ÷ 1 hr = km ÷ 60 min = 1/60 km/min Distance = velocity × time = (½ × 72 × 1/60 km/min) × (5 min) = 36/60 × 5 km = 3 km
True or false a velocity of 50 rad per min is a linear velocity?
False.
What is the trigonometric formula for rotational velocity?
Velocity = Radius x RPM For example if a body of 32 Inches in diameter rotating at 3600 rpm, the velocity is calculated by Velocity = 32/2 * 3600 Velocity = 57,200 inches per minute Velocity = 57,200 Inches/min * 60 Min/Hr * 1ft/12in * 1 mi/5280 ft Velocity = 54.5 miles per hr
How do you calculate initial velocity with time and absorbance as the variables?
Convert the velocity Vmax from ΔA/min to nmol/min (milliunits, mU). For example: 1 Unit = 1 U = 1 μmol PNP formed per min 1 milli-Unit = 1 mU = 1 nmol PNP formed per min Extinction coefficient ε for PNP at 410 nm = 15,000 M-1 cm-1 And the pathlength = 0.34 cm if the velocity v is determined to be 0.294 ∆A/min (absorbance units per min), then: 0.294 ∆A /min * M/(15,000 A * 0.34 cm) = 0.0000196 M/min = 19.6 μM/min = = 19.6 μmol / (liter * min) = 0.0196 μmol / (ml * min) The enzymatic reaction was carried out in 250 μl solution, hence the velocity of the enzyme is 0.0196 μmol / (ml * min) * 0.25 ml = 0.0049 μmol/min = 4.9 nmol/min PNP generated. v = 4.9 nmol/min = 4.9 mU
Velocity of a car that travels 80 km in 38 min convert to meters and seconds?
distance = rate * time 80 km = r * 38 minute r = 80 km / 38 min * 1000 m/km * 60 seconds/minute = 4800000/38 ~= 126315.79 m/s
Evaluate whether the velocity of a jogger can be determined from the information that the jogger travels 2 km in 10 min?
No , because velocity is a vector quantity and it needs direction.
What unit is air velocity measured in?
Air velocity is typically measured in units of meters per second (m/s) or feet per minute (ft/min).
A train starting from rest attains a velocity of 72Km hr in 5 minutes. Assuming that the acceleration is uniform what is the distance travel by train while attained the velocity?
As the acceleration is uniform, the train has an average speed that is half the difference between the start and final velocities, which in this case is half the final velocity. 1 hr = 60 min 1 km/h = 1 km ÷ 1 hr = km ÷ 60 min = 1/60 km/min Distance = velocity × time = (½ × 72 × 1/60 km/min) × (5 min) = 36/60 × 5 km = 3 km
What distance will be traveled if you are going 120km for 3 min?
If you are traveling at a speed of 120 km/h for 3 minutes, the distance traveled would be 6 km. This can be calculated by converting 3 minutes to hours (3 min ÷ 60 min = 0.05 hrs) and then using the formula distance = speed × time.
If Joe rides south on his bike in a straight line for 15 min with an average velocity of 12.5km how far has he ridden?
Joe has ridden a distance of 3.125 km in 15 minutes since velocity is distance traveled divided by time taken.
What will be the distance traveled by a car after 90 minutes?
It depends upon the speed or velocity of the car for e.g. if speed is 100km/min then Distance = speed X time i.e. D= 100X90= 9000km
Is air velocity measured in cubic feet?
No, air velocity is typically measured in feet per minute (ft/min) or meters per second (m/s). Cubic feet is a measurement of volume, not velocity.
True or false a velocity of 50 rad per min is a linear velocity?
False.
What is the plane's velocity if it travels 100 km in 90 minutes?
The definition of velocity, or at least speed, is distance/(time at speed), in this instance 10/9 km/min. (In advanced mathematics, "velocity" is a vector quantity, with both a magnitude and a direction. In that instance, a direction would also be needed but was not stated in the problem.)
Running with an acceleration of 3 m min2 is speeding up 3 m min for every meter traveled True or false?
False. An acceleration of 3 m/min^2 means that the velocity is increasing by 3 m/min for every second traveled, not every meter traveled.
What is the trigonometric formula for rotational velocity?
Velocity = Radius x RPM For example if a body of 32 Inches in diameter rotating at 3600 rpm, the velocity is calculated by Velocity = 32/2 * 3600 Velocity = 57,200 inches per minute Velocity = 57,200 Inches/min * 60 Min/Hr * 1ft/12in * 1 mi/5280 ft Velocity = 54.5 miles per hr
The Distance Between Anaheim and Brea Mall?
The distance is 8.2 miles in 12 min with a current traffic: 14 min
