Projectile Motion Physics Problem

For #1, Use calculus to find the equation for V on the first 7 seconds of flight. Likewise use the same process to find the equation for V on the next 2 seconds of flight but this time use the value for acceleration due to gravity. For #2, provide a clear reference that the biker can really make it to the other side of the cliff safely. Focus in horizontal distance or range.Problem #1 From Ground Zero a test flight was launched. The flight starts from zero velocity and accelerates as it moves upward. The object is positively accelerated only at the first 7 seconds of its motion, the vertical upward acceleration of the object is described by a = (4.2 m/s") t. What is the speed of the object after 9 seconds? Problem #2 A daredevil biker plans to jump from cliff to cliff. Using a device, he measured the distance between the safe points of the cliff to be 50 meters. Upon knowing that he can leave a ramp at 30 kph he decided to proceed with the stunt. The ramp was fixed at 45 degrees from the horizontal. Can the biker make it to the other edge of the cliff safely? (The life of this biker depends on your analysis). Safe points 50 meters 2
