An elevator in a high-rise building goes up and down at the same speed. Starting at the ground floor, Rafael and Monica ride up five floors, a vertical rise of 20 m. The elevator stops for 10 s as Monica gets off. Rafael then goes back down two floors. Rafael’s entire trip takes 24 s. Taking the origin to be at the ground floor, draw position-versus-time and velocity versus- time graphs for Rafael’s trip.
