Answer:
Explanation:
The relationship between angular acceleration α and torque τ is given by :
Here,
is the moment of inertia. It depends on the mass and the distance from the axis of rotation.
is the angular acceleration
Hence, this is the required solution.
Answer:
<em>time = 6.9 s</em>
<em></em>
Explanation:
velocity of the plane v = 22.7 m/s
acceleration of the train a = -3.3 m/s^2
it finally comes to res, final velocity u = 0 m/s
time t = ?
using the equation
v = u + at
substituting, we have
0 = 22.7 + (-3.3)t
0 = 22.7 - 3.3t
3.3t = 22.7
t = 22.7/3.3 = <em>6.9 s</em>
Answer: - 0.75 m
Explanation: The displacement will be the sum of the slope of the graph within the given time. From time 8s to 16s, the slope m will be; Slope = (15 - 6) / (16 - 8) Slope = 9 / 8 From time 16s to 24s Slope = (15 - 0) / ( 16 - 2 Slope = -15 / 8 Displacement = 9/8 - 15/8 Displacement = -6/8
Displacement = - 0.75 m
Answer:
More the mass, greater the inertia
So the greatest inertia will be possessed by C. 10 lb bag of potatoes
