In 10 second horizontal distance travelled by plane is 980 m and vertical distance is 490 m so angle is tan^-1 (0.5)

A plane is moving with 98m/s velocity.An object is released from it so it have acceleration of "g". So g=v/t so velocity of object will be V=gt V=9.8×10=98m/s Now using tan x = 98/98=1 So value of tan x =1 So value of tanx is 1when X=45°
