Question

Find time of flight and range of the projectile along the inclined plane as shown in figure. `(g = 10 m//s^2)`

Answer 1

Correct Answer - A::B::C
Using the above equations with `alpha=0^@`
`T= (2(20)sin30^@)/((10)cos30^@) = 2.31 s`
`R = (20)^2/((10)cos230^@) [sin 30^@ + sin 30^@]`
`= 53.33 m.`
