It will be 4 times of original thus maximum speed would be 80cm/s
Answer:
(a). Energy is 64,680 J
(b) velocity is 51.43m/s
(c) velocity in mph is 115.0mph
Explanation:
(a).
The potential energy of the payload of mass is at a vertical distance is
.
Therefore, for the payload of mass at a vertical distance of , the potential energy is
(b).
When the payload reaches the bottom of the shaft, all of its potential energy is converted into its kinetic energy; therefore,
(c).
The velocity in mph is
Answer:
put the car on fire
Explanation:
if you put it on fire you would have a lot of light now
Answer:
15? I actually don't know
Explanation:
it is almost zero .this is because the distance and the electrostatic force are inversely proportional
