A child pushes a toy truck up an inclined plane. The lifting force is...
Select one:
a. the weight of the truck.
b. the length of the inclined plane.
c. the force the child uses to push the truck.
d. equal to the total amount of work done.

Respuesta :

The lifting force when a child pushes a toy truck up an inclined plane is  equal to the total amount of work done.

Work-energy theorem

The work-energy theroem states, the work done on an object is equal to the change in mechanical energy of the object.

The net force applied by the child on the truck, will create a lifting force on the object.

Fd - Ffd = k.E

Where;

  • Fd is the work done by the child
  • Ffd is the work done by friction
  • K.E is the kinetic energy of the truck

Thus, the lifting force when a child pushes a toy truck up an inclined plane is  equal to the total amount of work done.
