very quickly #5. The world's fastest roller coaster is at Six Flags Magic Mountain. At the start, riders are shot forward and then up
a tower. They then begin the backward descent. The cars reach speed of 160 km/h in 7 seconds during the descent.
From a point 100 metres from the foot of the tower, the angle of elevation to the top of the tower is 52º. Find the height of the tower, to the nearest metre.

Full Throttle

Ride Info. Here it is, the latest in a long history of world records set at Six Flags Magic Mountain: Full Throttle.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
