If a car increases its speed from 5 m/s to 25 m/s over 40 seconds. what is the acceleration?
Give the unit.
what is (25-5)/40 ?
A car increase its speed from 5 meters per second to 25 meters per second over 40 seconds, what is the acceleration
o.625
To calculate the acceleration, you need to use the formula:
Acceleration (a) = Change in velocity (Δv) / Change in time (Δt)
In this case, the change in velocity Δv is the final velocity (25 m/s) minus the initial velocity (5 m/s):
Δv = 25 m/s - 5 m/s = 20 m/s
The change in time Δt is the given time interval of 40 seconds.
Δt = 40 seconds
Now, let's substitute these values into the formula:
Acceleration (a) = Δv / Δt
Acceleration (a) = 20 m/s / 40 seconds
Simplifying the expression:
Acceleration (a) = 0.5 m/s²
Therefore, the acceleration of the car is 0.5 m/s².
The unit for acceleration is meters per second squared (m/s²).
