How long will it take a car to acceleration from 15.2ms to 23.Ms if the car has an average acceleration of 3.2m\s

2.43 s

Explanation:

Initial velocity is

Final velocity

Average acceleration is

Average acceleration is change in velocity in the given amount of time

Thus, 2.43 s is required to acquire that average acceleration with 23 m/s velocity .

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
