Given :
An object with weight 20 N was lifted to 0.5 meters.
To Find :
How high must you lift a 25 Newton book for it to have the same increase in potential energy as the given book.
Solution :
Since both have same potential energy :
Putting all given values in above equation :
Therefore, book with same potential energy is at a height of 0.4 m.

Answer:
<em>The bicyclist goes at 5 m/s</em>
Explanation:
<u>Motion With Constant Acceleration
</u>
It's a type of motion in which the velocity of an object changes uniformly in time.
The equation that rules the change of velocities is:
Where:
a = acceleration
vo = initial speed
vf = final speed
t = time
It's given a bicyclist is traveling at v0=+25 m/s and decelerates at . We are required to calculate the speed after t=5 seconds.
Applying the formula:
The bicyclist goes at 5 m/s
The distance from one crest to the next crest in a set of waves is called the wavelength. The distance from the crest of one wave to the equilibrium point is called frequency.
