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
If a car starts from rest and after 6 seconds it is moving at 42 ms what is the car's average acceleration?
If a car is moving 42 meters per second after 6 sectons, the average acceletion is 7 meters per second per second. It is an average, given two points of data, and it is not the instantaneous acceleration at any point in time.
What is the rate of acceleration for a car that reaches a speed of three meters per second?
Insufficient information.
A 2.15 kg book is dropped from a height of 1.6 meters what is its acceleration?
The acceleration of the book due to gravity can be calculated using the formula: acceleration = (2 * height) / (time^2) Given that the height is 1.6 meters and the book is dropped (no initial velocity), we can use the formula to find the acceleration.
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 acceleration of a full bottle of water dropped from adesk?
The acceleration of a bottle of water dropped from a desk is approximately 9.81 m/s^2, which is the acceleration due to gravity. This means that the bottle's speed increases by 9.81 meters per second every second it falls.
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 acceleration of the stone if it is dropped from the top of a tower?
The acceleration of the stone when it is dropped from the top of a tower is equal to the acceleration due to gravity, which is approximately 9.8 m/s^2 downward. This acceleration remains constant as the stone falls towards the ground, neglecting air resistance.
What is the velocity of freely falling objects 5 seconds after being dropped?
The velocity of a freely falling object 5 seconds after being dropped is approximately 49 meters per second (m/s) downwards. This is the velocity an object reaches due to the acceleration of gravity (9.8 m/s^2) acting on it.
A ball is dropped from a height of 128 meters Each time the all bounces to half of its previous height After one bounce the ball readches a height of 64 meters How high did the ball reach after the 7?
After the 7th bounce, the ball will reach a height of 1 meter. This is because after each bounce, the ball reaches half of its previous height. So, after 1 bounce it reaches 64 meters, after 2 bounces it reaches 32 meters, after 3 bounces it reaches 16 meters, and so on, until it reaches 1 meter after the 7th bounce.
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
Find the rate at which objects fall when dropped from a high altitude?
Objects fall at a rate of 9.81 meters per second squared due to the acceleration of gravity on Earth. This means that each second an object falls, it will be traveling 9.81 m/s faster than the previous second. This rate of acceleration continues until the object reaches its terminal velocity or hits the ground.
What is acceleration at instantaneous maximum velocity?
The acceleration at instantaneous maximum velocity is zero, as the velocity is not changing at that moment.
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.
