A girl riding her bicycle at a velocity of 5 m/s travels 400 m (about a quarter mile). How long did it take her to travel that far? Show your work, and put a box around your final
answer.

80 seconds

Explanation:

For this problem, we can use the formula: velocity = distance/time, as we are given two of the unknown values so we can solve for the third.

The variable we are finding is time, so we first need to rearrange the formula to solve for time:

time = distance/velocity

Now we can just plug in our given values and solve:

Velocity = 5m/s

Distance = 400m

t = 400/5

t = 80

It took her 80 seconds to travel that far.

Hope this helped!

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
