Ahorizontal force in used to pull a 5 kilogram cart at a constant speed of 5 meters per second across the floor as shown in the diagram. if the force of friction between the cart and the floor is 10 newtons, the magnitude of the horizontal force along the handle of the cart is? a. 5n b. 10 n c. 25 n d. 50 n

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.)
