10\,\text{N}

force? a)

10\,\text{N}

force exerted by Earth on the cart directed downward b)

10\,\text{N}

force exerted by the student’s hand on the rope directed to the right c)

10\,\text{N}

force exerted by the cart on the rope directed to the left d)

10\,\text{N}

force exerted by the cart on the rope directed to the right
