Questions
The angle which the velocity vector of a projectile thrown with a velocity v at an angle θ to the horizontal will make with the horizontal after time t of its being thrown up is
detailed solution
Correct option is D
See fig. (5). Here v′cosα=vcosθand v′sinα=vsinθ−gt∴ V′sinαV′cosα=Vsinθ−gtVcosθ or tanα=Vsinθ−gtVcosθα=tan−1(Vsinθ−gt)VcosθTalk to our academic expert!
