A helicopter is traveling at 50 m/s at a constant altitude of 100 m over a level field.If a wheel falls off the helicopter,with what speed will it hit the ground? (g = 9.8 m/s² and air resistance negligible)

Question

Quizplus · Accepted Answer

The horizontal speed remains 50 m/s. The vertical speed upon impact can be calculated using the equation v = sqrt(2gh) = sqrt(2*9.8*100) = 44.3 m/s. The resultant speed is sqrt(50^2 + 44.3^2) = 67 m/s.
