A 40 lbs person is riding her bike weighing 15 lbs toward south at speed of 1 mile/hr when it collides with a car going west. As the result of the strike, the bike along with the biker are thrown 55 feet toward west. How fast the car was driving?

Is it possible for a body to have two dimensional velocity but one dimensional acceleration?
