Kinetic energy= 1/2 m v^2
so... 1/2(1350)(12^2)
kinetic energy = 97200Joules
Answer:
During start total turns
After half of the time total turns
Total number of turns during it stop
After half of the time total turns
Explanation:
Initially the machine is at rest and then starts rotating with speed 3550 rev/min
now we will have
now we know that it took 10 s to reach the speed
so angular acceleration is given as
now it stops in 31 s so the angular deceleration is given as
now initially number of turn to reach the given speed
number of turns during it stop
Now during startup speed after t = 5 s is given as
now during it stop the speed after half the time is given as
now the number of turns is given as
That statement is false. Stored energy is potential energy. Kinetic is a word that refers to motion. Kinetic energy is the energy of motion not stored energy.
Answer: Solid
Explanation: Most of the outer part of our planet is solid. This solid mantle sits on an outer liquid core and a solid inner core.
