Answer:
The slope of a position-time graph can be calculated as:
where
is the increment in the y-variable
is the increment in the x-variable
We can verify that the slope of this graph is actually equal to the velocity. In fact:
corresponds to the change in position, so it is the displacement,
corresponds to the change in time
, so the time interval
Therefore the slope of the graph is equal to
which corresponds to the definition of velocity.
Answer:
Torque = 99.48 N-m²
Explanation:
It is given that,
Radius of the flywheel, r = 1.93 m
Mass of the disk, m = 92.1 kg
Initial angular velocity,
Final angular speed,
We need to find the constant torque required to stop it in 1.25 min, t = 1.25 minutes = 75 seconds
Torque is given by :
...........(1)
I is moment of inertia, for a solid disk,
is angular acceleration
..............(2)
Now finding the value of angular acceleration as :
..........(3)
Using equation (2) and (3), solve equation (1) as :
So, the torque require to stop the flywheel is 99.48 N-m². Hence, this is the required solution.
