a plane stops from 250 mph in 25 seconds.
Calculate the planes acceleration
To calculate the plane's acceleration, we can use the formula:
Acceleration = (final velocity - initial velocity) / time
Given that the initial velocity (u) is 250 mph, the final velocity (v) is 0 mph (since the plane stops), and the time (t) is 25 seconds, we can substitute these values into the formula to find the acceleration.
Acceleration = (0 - 250) mph / 25 seconds
Simplifying, we get:
Acceleration = -250 mph / 25 seconds
Acceleration = -10 mph/s
Therefore, the plane's acceleration is -10 mph/s. The negative sign indicates that the velocity is decreasing or decelerating.
To calculate the plane's acceleration, we can use the formula:
acceleration = (final velocity - initial velocity) / time
In this case:
- The initial velocity is given as 250 mph.
- The final velocity is 0 mph because the plane stops.
- The time is given as 25 seconds.
First, let's convert the initial velocity and final velocity from mph to meters per second (m/s) since acceleration is typically measured in SI units.
1 mph is equal to 0.44704 m/s. Therefore, the initial velocity is 250 mph * 0.44704 m/s = 111.76 m/s.
Now we can substitute the values into the formula:
acceleration = (0 m/s - 111.76 m/s) / 25 s
Simplifying this equation gives:
acceleration = -111.76 m/s / 25 s = -4.47 m/s²
The plane's acceleration is -4.47 m/s² (negative because it decelerated).
swag
Vo = 250mi/h * 1600m/mi * (1/3600)h/s =
111.11m/s.
a = (Vf - Vo) / t,
a = (0 - 111.11) / 25 = -4.44m/s^2.
