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
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
How many revolutions would a tire make in 45 sec if its anguar velocity were 35 rev min?
There are 60 sec in one min 35 rev/min x 45/60 = 26.25 revs

What is a normal walking rate?
Average adult walking velocity on level surfaces is approximately 80 m/min. For men, it is about 82 m/min, and for women, about 79 m/min

You drive for 30 min for 30 km East and then another 30 min for 40 km North What if your average velocity for the entire trip is?
70km/h
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.
