Given your understanding of elasticity, which is a better example of something with elasticity: a rubber band or silly putty? explain why.

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

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
