Question

37. A plane is moving horizontally with constant velocity ejects a package from it to an observer on groundthe package falls with a speed 10 m/s at an anglewith horizontal and to the pilot it seems vertical witha speed 8 m/s at the same instant. The actual speed of plane is(1) 36 m/s(2) 6 m/s(3) 3 m/s(4) 4 m/s
