A notebook sitting on a desk has 19 j of potential energy. What is the total mechanical energy of the notebook?
Alex17521 [72]

The total mechanical energy of the notebook is <u><em>19J</em></u>.

Mechanical energy is the sum of potential energy and kinetic energy.  It has no kinetic energy, because it's not moving.  So its potential energy is all the  mechanical energy it has.

A force of 825 N is needed to push a car across a parking lot. Two students push a car 35 m. How much total work is done?
MaRussiya [10]
<h2>Answer :</h2><h2 />

Work is the amount of energy transferred. As per the formula

Work = Force x Distance [moved toward the direction of the force]

So as per the formula

<u>Solution : </u>

Force = 825 N

Distance = 35 m

Work = 825 (n) x 35 (m)

Work = 28875 Joules

According to the Guinness Book of World Records (1990 edition, p. 169), the highest rotary speed ever attained was 2010 m/s (450
Valentin [98]

When a body performs a uniform circular motion, the direction of the velocity vector changes at every moment. This variation is experienced by the linear vector, due to a force called centripetal, directed towards the center of the circle that gives rise to centripetal acceleration, the mathematical expression is given as,

a = \frac{v^2}{r}

Where,

v =  Tangential Velocity

r = Radius

The linear velocity was 2010m/s in a radius of 0.159m, then the centripetal acceleration is

a = \frac{2010^2}{0.159}

a = 2.54*10^7m/s^2

Therefore the centripetal acceleration of the end of the rod is 2.54*10^7m/s^2
