A car is traveling at 15 m/sec. Ten minutes later it is traveling at 70 m/sec. What is the acceleration?
4.7 m/s/m
To calculate the acceleration, we need to use the formula:
acceleration (a) = (final velocity - initial velocity) / time
Here, the initial velocity (u) is 15 m/sec, the final velocity (v) is 70 m/sec, and the time (t) is 10 minutes.
First, let's convert the time from minutes to seconds since velocity is given in meters per second:
10 minutes = 10 * 60 = 600 seconds
Now we can substitute the values into the formula:
a = (70 m/ sec - 15 m/sec) / 600 sec
Simplifying the equation:
a = (55 m/sec) / 600 sec
a = 0.0917 m/sec^2
Therefore, the acceleration of the car is approximately 0.0917 m/sec^2.
