Feet per second square ARE the units in this case.
Initial velocity can be measured in the same units as any other velocity. In SI, that would be meters per second, but often km / hour are used, or (in a minority of countries) feet/second or miles/hour.
feet
Impossible because area is measured in square units whereas volume is measured in cubic units.
FEET
Speed can be measured in units such as meters per second (m/s) or kilometers per hour (km/h).
Velocity is the rate of change of an object's position in a specific direction. Its units include meters per second (m/s), kilometers per hour (km/h), and feet per second (ft/s). Velocity is a vector quantity as it has both magnitude (speed) and direction.
They must have compatible units of measure. For example, you cannot directly add a quantity measured in meters to a quantity measured in centimeters. If their units of measure are compatible but not identical, one can be converted to the other. On the other hand, there is no way to add a quantity in feet to a quantity in pounds, as those are incompatible units of measure. Additionally, if the quantities are fractions, they must also have the same denominators, also called sharing a common denominator.
Speed or velocity can be measured in a number of units. Miles per hour, feet per second, metre per second.
An area is measured in square units, so for lengths measured in feet, the area would be measured in square feet.The surface area of a box, is just the sum of the areas of each face, each of which is measured in square units.
In SI, acceleration is measured in meters / second2, or meters / second / second. In other units, units of the same dimension have to be used, i.e., [length] / [time] / [time]. For example, in the imperial units, feet per square second is quite common.
The amount that something can hold refers to its capacity or volume, which describes the maximum quantity or volume of material it can contain. This can be measured in units such as liters, gallons, or cubic feet, depending on the item being measured.
Feet per second square ARE the units in this case.
Jerk is measured in units of meters per second cubed (m/s^3). It is a measure of the rate of change of acceleration over time.
Air velocity is typically measured in units of meters per second (m/s) or feet per minute (ft/min).
It could me any measure of volume per time. In the USA it is commonly measured as Cubic-Feet per Second.
Area is measured in square units - volumeis measured in cubic units
