An MBDA official investigated an accident in Roman highway. They saw a 200- feet-long skid mark which was produced from the time driver stepped on the car break to the time it fully stopped. During the investigation, the driver told him that after stepping on the car break, it decelerated at a speed of 16ft/sec2. The official wanted to know how fast the car was before the accident happened. Determine the car's velocity before the break is applied to help them dig on what caused the accident.
