When a plane is taking off on a runway the wind velocities at the top and bottom of the wings are found to be 40 ms^(-1) and 30 ms^(-1) respectively. If the wing span is 60 m^(2) find the dynamics lift on the density of air is 1.27 kg m^(-3) .

If the maximum height and range of a projectile are 3 m and 4 m respectively, then the velocity of the projectile is (Take, g = 1o ms^(-2) )
