Answer:
80 Percent
Explanation:
E=energy output/energy input×100
E=8000/10000×100
E=0.8×100
E=80 percent.

Answer:
Minimum speed will be equal to 2.213 m/sec
Explanation:
We have given radius of the r = 2 m
Coefficient of friction
At minimum speed frictional force will be equal to centripetal force
So
So the minimum speed will be equal to 2.213 m/sec

Answer:
I think it has something to do with both inertia and gravity?
Answer:
F = ma
Explanation:
If mass = m
Acceleration = a
Force = F
Force can be calculated by the product of mass and acceleration.
That is F = ma
This equation is gotten from newton's second law of motion which states that the rate of change of momentum of a body is proportional to the applied force which takes place in the direction of force applied
