Answer:
63.0 N
Explanation:
We need to consider the resultant of the forces acting along the surface. We have two forces:
- The component of the pull parallel to the ground, which is given by
where is the angle between the force and the ground
- The frictional force, given by
where is the coefficient of friction, m = 20 kg is the mass of the box and g=9.8 m/s^2.
The box is moving at constant velocity, this means zero acceleration, so the equation of equilibrium becomes:
From which we can find the magnitude of the pull, F:
To solve this problem we will apply the concepts related to the centripetal force, for which it is necessary to equate it with the static friction force of the body. From this, we will clear the speed and replace with the given values. Our values are defined as,
Maximum velocity can be find out using centripetal force,
Must be equal to,
Therefore the maximum speed that he can travel through the arc without slipping is 9.93m/s
