Magnitude of acceleration =
(change in speed) / (time for the change) =
(100 - 0)/10 = (10 km/hr-sec) x (1 hr/3,600 sec) = 0.00278 km/sec2 or 36,000 km/hr2 .

If a rock is dropped and it's speed increases from 0 to 4.9 in about 3 seconds. what is the acceleration?
Assuming that your units of velocity are in units/second Acceleration = (velocity 2 - velocity 1) / time Acceleration = (4.9 - 0) / 3 Acceleration =1.63 *With correct significant figures the answer is 2
An arrow in flight has an initial velocity of 65 meters per second and 10 seconds later it has a velocity of 35 meters per second Which is the acceleration of the arrow?
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
Why the second is squared in acceleration?
it is very simple........... velocity or speed = distance / time. acceleration = velocity / time but, we know that velocity = distance / time so just substitute the equation of velocity in acceleration...... so, finally we get , acceleration = distance/time*time so it is time squared.
How do you work out velocity when given acceleration and time?
Answer: v=u + at v (Velocity) = u (Starting velocity) + a (acceleration) x t (time) So, starting from stationary (u=0), the velocity is simply a x t e.g. if the acceleration is 5mph per second per second, after 10 seconds you would be travelling at 50mph. Answer: The above is for constant acceleration. In the case of variable acceleration, integration has to be used.
What is acceleration time graph?
The change in the velocity divided by time in meters per second squared.
What can Acceleration be defined as?
Velocity divided by time. The amount the the velocity increases by per second.

When the body is drop how is velocity related to the time?
If air resistance is negligible, velocity increases at a rate of 9.8 meters / second every second, that is to say, the acceleration is 9.8 meters per second square.
What is her acceleration if 'acceleration is defined as a change in velocity over time. If a runner increases velocity from 2 ms to 4 ms over a period of 20 seconds?
It is 0.1 metre per second-squared.
What is the units acceleration?
Acceleration is the rate at which an object's velocity changes over time and its unit is meters per second squared (m/s^2). This means that for every second that passes, the velocity of the object increases or decreases by a certain number of meters per second.
What is the amount by which the speed increases in one second?
It is the acceleration.
What is a car's acceleration if it increases its speed from 5 miles per second to 20 miles per second in 3 seconds?
The acceleration of the car can be calculated using the formula: acceleration = change in velocity / time. In this case, the change in velocity is 20 - 5 = 15 miles per second. So, the acceleration is 15 miles per second / 3 seconds = 5 miles per second squared.
How are veloc ty and acceleration related?
Velocity and acceleration are related in that acceleration is the rate of change of velocity over time. If an object is accelerating, its velocity is changing. A positive acceleration means the object is speeding up, while a negative acceleration means the object is slowing down.
What is acceleration and its si unit?
Acceleration is the rate of change of velocity - how fast a velocity changes. Therefore, its units are naturally (meters/second) / second, usually written as meters/second2.Acceleration is the rate of change of velocity - how fast a velocity changes.

What is the rate of acceleration of an object in free fall on earth?
The rate of acceleration of an object in free fall on Earth is approximately 9.8 m/s^2, and it is due to the acceleration caused by gravity. This means that the object's velocity increases by 9.8 meters per second every second it falls.
What is the the amount by which the speed increases in one second called?
It is the acceleration.
What is the description of constant acceleration?
Constant acceleration is a type of motion where the velocity of an object changes at a constant rate over time. This means that the object's speed increases or decreases by the same amount every second. It can be described mathematically by the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.
