16 feet/second is the speed. To know the velocity, you would also need to specify the direction in which the object moves.
I assume the object starts from rest. The speed will be 16*3 which is 48m/s
"Per second per second" is a measurement of acceleration. If an object (such as a car) is moving, its speed can be measured in terms of miles per hour, or feet per second (which work out to be a similar figure to miles per hour). If the car is accelerating, the acceleration can be measured in terms of additional speed (feet per second) that is acquired in a given second, therefore, feet per second per second. Get it?
Neglecting the effect of air resistance, the speed of any falling object ... including ice cubes ... is always 32.2 feet per second greater than it was one second earlier.
20 feet per second. Divide the distance travelled by the time taken - so 180 / 9 = 20
Depend on if you are talking a "free-fall" or an object descending the side of a mountain. Free-fall all objects regardless of weight fall at the same rate of speed (36 feet per second).
The speed of the object is 6.6 feet per second, calculated by dividing the distance traveled (33 feet) by the time taken (5 seconds).
To determine feet per second, divide the distance in feet by the time in seconds it takes to cover that distance. The formula for calculating speed is Speed = Distance / Time. For example, if an object travels 60 feet in 10 seconds, the speed would be 60 feet / 10 seconds = 6 feet per second.
The speed of free fall is approximately 9.8 m/s², which is the acceleration due to gravity on Earth. This means that an object in free fall will increase its speed by 9.8 meters per second for every second it falls.

Well, Speed is not the same thing as Acceleration. But to answer you question the best I can: the numerical value of speed can be higher than the numerical value of acceleration - for example, an object can have a speed of 10 feet per second while accelerating at 2 feet per second squared.
I assume the object starts from rest. The speed will be 16*3 which is 48m/s
I am assuming you actually did mean acceleration and not speed or velocity. Acceleration already implies a change in speed or velocity, either increasing or decreasing. For an object to change speed -- in other words, for an object to accelerate -- the sum of the forces acting upon it must be non-zero. But you asked about an increase in acceleration! That's a bit different. The change in acceleration is called jerk, which requires a bit of explanation. If you drop an object off a tall tower in a vacuum on Earth, that object will experience constant acceleration; that is, its speed will increase at a constant rate. At the end of its first second of freefall, it will achieve a speed of 32 feet per second; at the end of its second second of freefall, it will reach 64 feet per second; and at the end of its third second, it will be falling at 96 feet per second. You can see that the change in speed from one second to the next is always 32 feet per second, which implies a constant acceleration. Since the object is accelerating, we know that the sum of the forces acting upon the object is something other than zero. In fact, the force acting upon the falling object is its weight, and since there's nothing to counteract its weight, the object falls at constantly increasing speed. But what if the object reached 32 feet per second in the first second and 64 feet per second in the next and 128 feet per second in the next?! You can see that the difference in speed from one second to the next is not constant; it's increasing. That implies that the force acting on the object is not constant but is also increasing. That sort of thing happens in rocketry -- think of the space shuttle -- when the thrust forces created by the rocket motors increase greatly as they burn off fuel. A varying force will result in a varying acceleration, which is called jerk.

If you travel at 90 kilometers per hour, your speed would be approximately 82.6 feet per second. This conversion is based on the fact that 1 kilometer is equal to 3280.84 feet and 1 hour is equal to 3600 seconds.
If an object travels at a speed of 2.3 feet per second, it is also traveling at a speed of 8,280 feet per hour. (2.3 feet per second times 60 seconds per minute times 60 minutes per hour) If an object travels at a speed of 8,280 feet per hour, it is also traveling at a speed of 1.568 miles per hour. (8,280 feet per hour divided by 5,280 feet per mile)
