A projectile has the same range RGiven g 10 ms2ectile has the same range R 40 m for two angles of projection. If Ti and Th are the times of flight, find T T40 m for two angles of pr

Answer»

For same rangle... the angles should be complimentary to each other..

and the relationship between R , T1 and T2 is given by R = (T1)(T2)g/2

here R = 40

so , T1*T2 = 40*2/10 = 8
