A stressed physics student takes a break from labs and goes up to the roof of the lab sciences building. Standing next to the edge of the roof, the student tosses a ball upward at
2.81(m)/(s)from chest height - some
1.47mabove the roof - but misses catching it on its way back down. The ball then hits the ground
2.64safter being tossed. Given the time spent in the air, how tall (in
m) is the lab sciences building - that is, what's the distance from ground to roof?
