Answer:
W = 100000 J = 100 KJ
Explanation:
Here we will use the most basic and general formula of work, which is as follows:
where,
W = Work Done = ?
F = Force Required = 200 N
d = Length of Track = 500 m

<u>W = 100000 J = 100 KJ</u>
Answer:
The mass m is 0.332 kg or 332 gm
Explanation:
Given
The platform is rotating with angular speed ,
Mass m is moving on platform in a circle with radius ,
Force sensor reading to which spring is attached ,
Now for the mass m to move in circle the required centripetal force is given by
=>
Thus the mass m is 0.332 kg or 332 gm
