What is the rate of acceleration for a car that reaches a speed of three meters per second from rest in ten seconds?
0.3 meters per second
What is the average acceleration of a car that changes speed from 0 meters per second to 15 meters per second in 5seconds?
Average acceleration = change in speed/time for the change = 15/5 = 3 meters per second2 .
What is the average acceleration of a car that changes speed from 0 meters per second to 15meters per second in 5 second?
Average acceleration = (change in speed) divided by (time for the change) =(15 - 0) / (5) = 15/5 =3 meters per second2
An eagle accelerates from 15 meters per second to 22 meters per second in 4 seconds. What is the eagle's average acceleration?
Average acceleration is the amount of acceleration per unit of time that a thing or an object undergoes. It is simple to discover. To find the average acceleration, we need only find out how much acceleration occurred and over what period of time. If we have the starting and the ending speeds, then by subtracting them we can find the chane of acceleration. Then we can divide that acceleration by the time it took to occur. The eagle in our example accelerates from 15 m/s to 22 m/s over a period of 4 seconds. His total acceleration was 7 m/s (22 m/s minus 15 m/s = 7 m/s), and, since it took 4 seconds to increase his speed by 7 m/s, the average acceleration is the total acceleration divided by the time it took to happen (as was stated). The average acceleration is 7 m/s divided by 4 seconds or 1.75 meters per second.
A car traveling at 25 meters a second speeds up to 40 meters a second over a period of 15 seconds what is the average acceleration of the car?
Average acceleration = (change in speed) divided by (time interval)A = (40 - 25) / 15 = 15/15 = 1 meter/sec2
What is the rate of acceleration for a car that reaches a speed of three meters per second?
Insufficient information.
What is the rate of acceleration for a car that reaches a speed of three meters per second from rest in ten seconds?
0.3 meters per second
A 2.15 kg book is dropped from a height of 1.6 meters what is its acceleration?
If air resistance can be ignored, the acceleration is 9.82 meters per second square. Note that to get this result, neither the mass of the book, nor the height from which it is dropped, is relevant.If air resistance can be ignored, the acceleration is 9.82 meters per second square.

What is the acceleration of the stone if it is dropped from the top of a tower?
The acceleration will be equal to the acceleration due to gravity. Unless otherwise stated, one can assume this to be 9.81 meters/seconds It has nothing to do with the mass of the stone.
What is the average net force if a car with 1000kg reaches the speed of 28 meters per seconds in 7 seconds?
Acceleration = (change in speed) / (time) = 28/7 = 4 meters per second2Force = (mass) x (acceleration) = (1,000 x 4) = 4,000 kg-m/sec2 = 4,000 Newtons.
What is the average acceleration of a car that changes speed from 0 meters per second to 15 meters per second in 5seconds?
Average acceleration = change in speed/time for the change = 15/5 = 3 meters per second2 .
What is acceleration at instantaneous maximum velocity?
In the case of an object thrown, batted, teed off, or dropped, its acceleration at the instant of its maximum velocity is 9.8 meters per second2 downward.
What is the velocity of a ball dropped on the surface of Mars if the acceleration of gravity is 3.7 meters per second squared?
When given a constant acceleration, just multiply it by time, t, to detemine the final velocity. If the initial velocity was zero (as is the case when you drop something), then the average velocity is half the terminal velocity.
What is an acceleration that is 9.8 meters?
Acceleration is expressed in meters/second2, not in meters. Normal Earth gravity produces an acceleration of 9.8 meters/second2.
What is the acceleration if the velocity increases by eighty meters per second in twenty seconds?
Average acceleration = (change in speed) divided by (time for the change)= (80) / (20) = 4 meters per second2
What happens when a penny is dropped from a height of 20 meters?
It falls down. When it reaches a hard bottom it is likely to bounce whereas if it hits water it will sink.
If you drop an object it will accelerate downward at a rate of 9.8 meters per second squared if you instead throw it downwards its acceleration will be greater or less 9.8 meters per second?
Whether the object is dropped, thrown downwards, thrown upwards, or thrown horizontally, its downward acceleration is the same 9.8 meters per second2. If it's thrown downwards, however, its speed at any instant is greater than the speed at the same instant would be if it had only been dropped, since it has some speed before the acceleration begins.
