A ball thrown upwards hits a roof and returns back to the ground.
The upward movement is modelled by a function s=−t^2+3t+4 and the downward movement is modelled by s=−2t^2+t+7, where s is the distance (in metres) from the ground and t is the time in seconds.
Find the height of the roof from the ground.
Give your answer as a number without units.
