Ответ:
Velocity = √((Centrifugal force * radius)/mass)
Velocity = √(533 * 0.75 / 16.4)
Velocity = √(399.75 / 16.4)
Velocity = √24.375
Velocity = 4.9 m/s
Ответ:
Not sure as this is more physics than chemistry, but here is my best guess. Maybe someone with more knowledge of physics will weigh in.
-0.005 kg x 9.8 m/s2 + 1.5 N = 0.005 kg
-0.049 N + 1.5 N = 0.005 kg
1.451 N = 0.005 kg
1.451 kg-m/s2 / 0.005 kg = 290 m/s2 acceleration
