Bill is driving a very old car with a hood designed to be rigid in a crash. Linda is driving a new car with a hood designed to crumple in a crash. Both have the same mass and are wearing
seat belts. In a head-on collision at the same speed with a stationary wall, which driver will
experience greater force?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° 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.)
