A model railroad train travels at a constant speed of 8 cm/s . How far would the train travel in one minute ?

480cm or 0.48m

Explanation:

Given parameter:

Speed of the train = 8cm/s

time of travel = 1minute

Unknown:

Distance traveled = ?

Solution:

Speed is the rate of change of distance with time. This suggests that mathematically;

         Speed =  

       Distance covered = speed   x   time

Now to solve for the distance;

 Convert the time to seconds;

             60seconds = 1 minute

 Distance covered = 8cm/s  x 60s = 480cm

Distance covered is 480cm or 0.48m

come closer and become far apart and become steam/gas

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.
