Answer:
velocity 1 second later = 59.8 m/s
Explanation:
Velocity final = Velocity initial + acceleration • time
Velocity final = 50m/s + 9.8m/s/s • 1s
Velocity final = 59.8 m/s
By definition,
density = mass/volume
The mass is 82 g
The volume is 14 cm³
Therefore
density = (82 g)/(14 cm³) = 5.857 g/cm³
In SI units, density = 5857 kg/m³
Answer: 5.857 g/cm³
