A rock of mass m is hanging on a rope. The rock is moving upward and speeding up. How does the magnitude F of the force exerted on the rock by the rope compare with the magnitude of mg of the gravitational force

i need to show me the graph so i can give u an answer

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

i think the answer is a and b

i wish you luck
