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
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 change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
Divide the difference in speed by the time. You must convert the speed difference into meters/second (dividing km/h by 3.6).
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
Assuming that acceleration is constant during that time, just divide the change in speed by the time.
smart
Acceleration is when speed increases. Deceleration is when speed decreases.
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.

Average acceleration = (change in speed) divided by (time for the change)= (80) / (20) = 4 meters per second2

It is the velocity that increases.
Acceleration is determined by the net force acting on an object and the object's mass, as described by Newton's second law of motion (F=ma). The greater the force applied to an object, or the lighter the object's mass, the greater the acceleration. Acceleration always occurs in the direction of the net force.
It is the acceleration.
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)
The speed at which an object falls and the acceleration at which it falls are not the same value. The acceleration due to gravity is constant at about 9.8 m/s^2 near the surface of the Earth, but the speed of an object can change as it falls depending on factors such as air resistance.
Divide the difference in speed by the time. You must convert the speed difference into meters/second (dividing km/h by 3.6).
