Detailed explanation and calculation is shown in the image below
Answer:
23.52092 J
Explanation:
m = Mass of block = 6.79 kg
s = Sliding distance = 2.82 m
= Angle of slide = 20.7°
= Coefficient of kinetic friction = 0.425
g = Acceleration due to gravity = 9.8 m/s²
Work done by the force of gravity is given by
The work done by the force of gravity is 23.52092 J
Since the boot-print was left there nearly 50 years ago, there has been very little wind and very little rain in that area, and plus, there have been very few people or other animals walking around in that spot to disturb it.
Answer:
The arrow rise 44.64 m high assuming air friction is negligible
Explanation:
According to the law of conservation of energy
Kinetic energy = Potential energy at highest
----1
We know that F=kx
So,
Substitute the value in 1
Hence the arrow rise 44.64 m high assuming air friction is negligible
Answer:
The automated system that uses an automated work cell controlled by electronic signals from a common centralized computer facility is "Robotics"
Explanation:
Robotics is an advanced technology fully automated which uses electronic sensors incorporated with the combination of control into mechanical systems greatly enhancing the performance and flexibility of the systems. This is possible with the advances in hardware, software, and control programming systems which amounts to extensive automation from a common centralized computer facility.
