The world's fastest roller coaster is at Six Flags Magic Mountain. A the start, riders are shot forward and then up a tower. They then begin to the backward descent. The cars reach a speed of 160/km/h in 7 s during the descent. From a point 100 m from the foot of the tower, the angle of elevation of the top of the tower is 52 degrees. Find the height of the tower to the nearest metre.
