Why is it that a cat that accidentally falls from a 50-story building hits a safety net below with the same speed as if it fell from a 20-story building?
When Fatima rides her bicycle at 5 m/s, the drag force acting on her and her bicycle is 6 N. If she speeds up to 10 m/s, how large will the drag force become?
A passenger is standing on a scale in an elevator. The building has a height of 500 feet, the passenger has a
mass of 80 kg, and the scale has a mass of 7 kg. The scale sits on the
oor of the elevator. You may take g
= 10 N/kg. While it is accelerating downwards hat does the scale read (in newtons
