Will give ! 1 the velocity of a car reduces from 30 km/h to 5 km/h as the car approaches a stop sign. is this an example of positive or negative acceleration? (circle the correct answer)

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
