When the truck broke through the guardrail it was launched from the freeway with a horizontal velocity of 10.7 m/s and fell a vertical distance of 50 feet (15.2 m). a) Draw a simplified sketch showing the trajectory of the truck being launched horizontally with the velocity of 10.7 m/s. b) Determine the time that it would take for the truck to freefall the 50 feet( 15.2 m). c) Ignoring air resistance and scraping the building on the way down, determine the instantaneous velocity of the truck just before impacting the ground.
