Answer:
Explanation:
Initial angular speed of the ferris wheel is given as
final angular speed after friction is given as
now angular acceleration is given as
now torque due to friction on the wheel is given as
Now the power required to rotate it with initial given speed is
Newton's second law states that the resultant of the forces applied to an object is equal to the product between the object's mass and its acceleration:
where in our problem, m is the mass the (child+cart) and a is the acceleration of the system.
We are only concerned about what it happens on the horizontal axis, so there are two forces acting on the cart+child system: the force F of the man pushing it, and the frictional force
acting in the opposite direction. So Newton's second law can be rewritten as
or
since the frictional force is 15 N and we want to achieve an acceleration of
, we can substitute these values to find what is the force the man needs:
