What is the magnitude and direction of the net force on the box in the diagram? Remember that opposite forces are subtracted from each other.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
