What is the velocity of a ball thrown at 16 feet per second?
16 feet/second is the speed. To know the velocity, you would also need to specify the direction in which the object moves.
What is speed of object at 3 seconds given an acceleration of 16 feet per second squared for 3 seconds?
I assume the object starts from rest. The speed will be 16*3 which is 48m/s
Explain per second per second?
"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?
What is Feet per second of a falling ice cube?
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.
What is the average speed of an object that moves 180 feet in 9 seconds?
20 feet per second. Divide the distance travelled by the time taken - so 180 / 9 = 20
If weight is added to a object will it go fast or slow?
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).
If an object moved 33 feet in 5 seconds what is its speed?
Speed = (distance) / (time) = 33/5 = 6.6 feet per second
What is the speed of free fall?
There is no definite speed for free falling. If an object is released somewhere above the earth, the speed is changing every single moment. It is never the same speed it was before at any time; only until an object releases terminal velocity where it is moving at a constant speed. This is different for every object. The acceleration due to the gravity of the earth is 32 feet/second^2. This means that for every second that passes, an object is moving 32 feet/second faster than it was the second before.
What is your speed in feet per second if you travel at 90 kilometers per hour?
At 90 km/h an object is moving at about 82.021 feet per second.
If an object is in free fall after each second how does the object fall?
The speed of an object in free fall near the earth's surface is always 9.8 meters (32.2 feet) per second morethan it was one second earlier.
What is the velocity of a 4.5 Pound object falling thirty feet?
Ignoring air resistance ... Any object dropped near the Earth's surface reaches a speed of 43.9 feet per second after falling 30 feet. The velocity is 43.9 feet per second down. The object's weight makes no difference.
What is the velocity of a ball thrown at 16 feet per second?
16 feet/second is the speed. To know the velocity, you would also need to specify the direction in which the object moves.
Can speed exceed acceleration?
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.
What is speed of object at 3 seconds given an acceleration of 16 feet per second squared for 3 seconds?
I assume the object starts from rest. The speed will be 16*3 which is 48m/s
What causes acceleration to increase?
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.
What is speed of a freely falling object ten seconds after starting from rest?
98 meters (322 feet) per second.
