A Speedster car is traveling at a constant speed of 30m/s when it passes a stationary police car. one second after the car passes the police car
Start from rest and accelerates at a constant rate of 7,50 m/s to chase the speeding car. How long afterwards will the police
car catch up with the speeding car?

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

Which is the most accurate name for the covalent compound p2o3?
