It is 800 N FN = 600N + 200 N = 800 N Answer to your question: The net force is all Newton's second law. It is the force that acts on a body or a particle. for example: It is the force we make when we push a car or something heavy that is in a straight line. .
A) <u>Weight = mass × acceleration (due to gravity) </u>
= 60×9.8
= 588 N
<u>B) Potential energy = mass x gravity x change in height
</u>
1,000 = 60.0 x 9.8 x h
h = 1.7 m
<u>C) Kinetic energyF = potential energyI
</u>
KEF = 1/2mv2
PEI = mgh = 1,000 J
1/2mv2 = 1,000
1/2(60.0)v2 = 1,000
v2 = 33.33
v = 5.77 m/s
Answer:
Explanation:
Generally the workdone in moving the proton is mathematically represented as
Where
So
Here is the velocity at A with value 50 m/s
So
Also
Here is the velocity at A with value
=>
=>
So
Now this workdone is also mathematically represented as
So
Here
So
Generally proton movement is in the direction of the electric field it means that
So
Answer:
55
