What is a cars acceleration if its speed increases from 50 kilometers per hour to 80 kilometers per hour in six seconds?
well we know that we have two speeds and a time. So,
initial speed = 80
final speed = 60
change in time = 6
Now acceleration in this case will be measured in kilometers per hour per second (i.e. every x seconds, y kilometers per hour are gained in speed)
So we simply apply the formula
Acceleration = (final speed - initial speed)/ change in time
= (80 - 60)/6
= 20/6
= 3.6666667 km/h/s

What is the acceleration of a car moving along a straight line path that increases its speed from zero to 100 kilometers per hour in ten seconds?
If you want to have that in meters per second square, convert the speed to meters per second (divide by 3.6 in this case). Then, divide the speed by the time.
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
What is the acceleration of a car if its speed increases from 80 to 90 kilometer per hour in 2 seconds?
Divide the difference in speed by the time. You must convert the speed difference into meters/second (dividing km/h by 3.6).
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
Acceleration is defined as a change in velocity over time if a runner increases velocity from 2 m s to 4 m s over a period of 20 seconds what is the acceleration?
Assuming that acceleration is constant during that time, just divide the change in speed by the time.
What is the acceleration of a vehicle that changes its speed from 100 kilometers per hour to 0 kilometers per hour in 10 seconds?

What is the amount by which the speed increases in one second?
It is the acceleration.
What is the the amount by which the speed increases in one second called?
It is the acceleration.
What is the acceleration of a car moving along a straight line path that increases its speed from zero to 100 kilometers per hour in ten seconds?
If you want to have that in meters per second square, convert the speed to meters per second (divide by 3.6 in this case). Then, divide the speed by the time.
How does a change in speed affect acceleration?
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.
Why speed increases if its acceleration decreases?
stamina
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 is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
When a ball increases in speed by the same amount each second its acceleration is?
When a ball increases in speed by the same amount each second, its acceleration is constant. This type of motion is known as constant acceleration.
