A student catches a can of soda dropped from some unknown height by Mr. Fineman. If the can was dropped from rest, and it is traveling at 8.9 m/s before it arrives in the student's hand...
a. How long was the can in free fall for?
b. From what height was the can of soda dropped?

Which force is most responsible for binding together an atom's protons and neutrons? electrostatic gravitational nuclear magnetic

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j

Anybody wanna ? (picture included? )
