Two balls are thrown from an inclined plane at angle of projection `alpha` with the plane, one up the incline and other down the incline as shown in figure (`T` stands for total time of flight):

Options

A. `h_(1) = h_(2) (v_(0)^(2)sin^(2)alpha)/(2gcos0)`
B. `T_(1)=T_(2) = (2v_(0)sinalpha)/(gcos0)`
C. `R_(2)-R_(1)=g(sin0)T_(1)^(2)`
D. `v_(t_(2))=v_(t_(1))`

Answer

A, B, C
