Answer:
The centripetal acceleration changed by a factor of 0.5
Explanation:
Given;
first radius of the horizontal circle, r₁ = 500 m
speed of the airplane, v = 150 m/s
second radius of the airplane, r₂ = 1000 m
Centripetal acceleration is given as;
At constant speed, we will have;
a₂ = 0.5a₁
Therefore, the centripetal acceleration changed by a factor of 0.5
Answer:
v=3.649 m/s
Explanation:
Lets start with the force of gravity on the elevator.
But the friction clamp opposes this with a force of 17000 N
So the Net force on the elevator is
Kinetic Energy
The motion will be describe
original Kinetic energy + work done = final kinetic energy + spring energy
The more resistance you have the more you
have to push to make a current flow
