Answer:
The angular speed after 6s is .
Explanation:
The equation
relates the moment of inertia of a rigid body, and its angular acceleration , with the force applied at a distance from the axis of rotation.
In our case, the force applied is , at a distance , to a ring with the moment of inertia of ; therefore, the angular acceleration is
Therefore, the angular speed which is
after 6 seconds is

Answer: 7840N
Explanation:
Given that
Potential energy = ?
Mass of sled = 20-kg
Distance = 40 meters
Acceleration due to gravity = 9.8m/s^2
Recall that potential energy is the energy possessed by a body at rest
i.e potential energy = mass m x acceleration due to gravity g x distance h
P.E = mgh
P.E = 20kg x 9.8m/s^2 x 40m
P.E = 7840N
Thus, the potential energy of the sled is 7840N
