Answer:
Power delivered will be 10755.87 W
Explanation:
We have given mass of elevator m = 591 kg
Time t = 4.79 sec
As the elevator starts from rest so initial velocity u = 0m/sec
Final velocity v = 2.17 m/sec
From first equation of motion
v=u+at. here v is final velocity, u is initial velocity and t is time
So
Height is given by
As elevator moves upward and acceleration due to gravity is downward so net acceleration due to gravity is downward so net acceleration = g-a=9.8-0.453 = 9.347
Now work done
We know that power
Answer: Gemini
Explanation: lol I just born that that sign ig
Answer:
<h2>9.52 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>9.52 m/s²</h3>
Hope this helps you
Because high school usually starts with students who are above 13 years of age
Answer:
Explanation:
The constant speed means that ball is not experimenting acceleration. This elements is modelled by using the following equation of equilibrium:
Now, the exerted force is:
The volume of a sphere is:
Lastly, the force is calculated:
