Did i get any of these answers right if not what do i have to change

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

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

Me with this and you will be marked brainliest
