Two balls are projected at different angles to acquire same horizontal

1.	Two balls are projected at different angles to acquire same horizontal range R with same initial speed u . If max height acquired by the balls are H1 and H2 resp, then (1)H1+H2=u2g (2)H1+H2= u22g (3)H1+H2=R24 (4) Both 2 and 3
Answer» Two balls are projected at different angles to acquire same horizontal range R with same initial speed u . If max height acquired by the balls are H1 and H2 resp, then (1)H1+H2= $\frac{u^{2}}{g}$ (2)H1+H2= $\frac{u^{2}}{2 g}$ (3)H1+H2= $\frac{R^{2}}{4}$ (4) Both 2 and 3

Answer»

Two balls are projected at different angles to acquire same horizontal range R with same initial speed u . If max height acquired by the balls are H1 and H2 resp, then

(1)H1+H2= $\frac{u^{2}}{g}$

(2)H1+H2= $\frac{u^{2}}{2 g}$

(3)H1+H2= $\frac{R^{2}}{4}$

(4) Both 2 and 3
