Yes, an object can have both of these at the same time. Potential energy is energy that is stored in an object. Kinetic energy is the energy that is associated with motion. So what you have to have is an object that is in motion but still has more energy that it has yet to convert into kinetic energy.
Answer:
translucent
Explanation:
you can see light coming thru but u cant see thru the glass.
Answer:
3.14946 rad/s
Explanation:
= Intial moment of inertia
= Final moment of inertia
= Initial angular velocity
= Final angular velocity = 

In this system the angular momentum is conserved

The angular velocity when the diver left the board is 3.14946 rad/s
C a meter stick with only centimeters
D a ruler with millimeters and centimeters
D would be to the nearest half milimeter. Take some time to measure with a 2 inch ruler. Would you really need to know the length to half a mil ?
