Aball dropped from rest falls freely until it hits the ground with a speed pf 20 m/s. the time during with the ball is in free fall is approximately

What is the momentum of a 2 kg object moving at 15 meters per second

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

How do you tell if someone actually cares about you? and just say they do?
