To calculate the average acceleration, you can use the formula ( a = \frac{\Delta v}{\Delta t} ), where ( \Delta v ) is the change in velocity and ( \Delta t ) is the change in time. In this case, the change in speed is from 0 m/s to 40 m/s, so ( \Delta v = 40 , \text{m/s} - 0 , \text{m/s} = 40 , \text{m/s} ). The time taken is 4 seconds, so ( \Delta t = 4 , \text{s} ). Thus, the average acceleration is ( a = \frac{40 , \text{m/s}}{4 , \text{s}} = 10 , \text{m/s}^2 ).
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)
If he started out from "rest" (zero speed), then his average acceleration for the 5 seconds is50/5 = 10 meters per second2
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2
Acceleration is the rate that speed changes.
You haven't mentioned distances or speed or acceleration, so this cannot be answered.
Average acceleration = Change in speed/time so Time = Change in speed/Average acceleration
Divide the difference in speed by the time it takes. This will give you the average acceleration for that time period.
The average rate of acceleration is (11/5) = 2.2 m/sec2 .
Acceleration is the rate at which speed changes, at least scalarly.

Acceleration is a measure of how quickly the speed of an object changes over time, not the speed itself. Speed refers to the rate at which an object covers distance, while acceleration refers to how the speed of the object changes. So, acceleration is not a kind of speed, but rather a measure of how speed changes.
