A car has a velocity of 25m and accelerates uniformly to 45m/s in 10seconds.what is the acceleration?
change in velocity divided by time.
(45-25)/10
To find the acceleration, you need to use the following formula:
acceleration = (final velocity - initial velocity) / time
First, let's identify the given values:
The initial velocity (u) is 25 m/s (the car's velocity at the beginning)
The final velocity (v) is 45 m/s (the car's velocity at the end)
The time (t) is 10 seconds (the time it takes for the car to accelerate)
Now substitute the values into the formula:
acceleration = (45 m/s - 25 m/s) / 10 seconds
Simplifying this equation:
acceleration = 20 m/s / 10 seconds
The units cancel out, and you are left with:
acceleration = 2 m/s^2
Therefore, the acceleration of the car is 2 m/s^2.
