A dirt biker races up a 15° incline and then takes off in an attempt to clear an obstacle. The end of the ramp is 3 m off the ground. A 4-m high obstacle is located 20 m from the base of the ramp.

What minimum take-off speed is required for the daredevil to clear the obstacle?
How long does it take to clear the obstacle?
What is the total time of flight?
Where will the daredevil land (relative to the edge of the ramp)?
