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

Text Solution

Verified by Experts

The correct Answer is:
A, C
`T = (2usin(alpha -beta))/(g cos beta)`
`((2)(20sqrt2)sin(45^@ -30^@))/((10)(cos 30^@)) = 1.69s`
`R = u^2/(gcos^2beta) [sin(2alpha-beta)-sinbeta]`
`=(20sqrt(2))^2/((10)cos^2 30^@) [sin(2xx45^@-30^@)- sin 30^@]`
`=39m`.
