A plane needs to reach a velocity of 300 km/h relative to the air in order to take off. If there is a wind blowing at 80 km/h in the direction opposite to take off, what velocity must the plane reach relative to ground in order to take off

Question

Nirmal Singh. · Answer

by relative motion v p,g = v p,w + v w,g where v p,g = velocity of plane w r t ground = ? v p,w = velocity of plane w r t wind = 300 Km.h v w,g = velocity of wind w r t ground = 80 km/hr v p,g = 300 + 80 = 380 Km/hr Thanks & Regards, Nirmal Singh Askiitians faculty
