A projectile is launched from the bottom of an inclined plane that makes an angle of 30∘ with the horizontal. The projectile is launched with a velocity of 20m/s at an angle of 60∘ relative to the horizontal. Find the range of the projectile along the incline. If the projectile bounces from the inclined surface with perfectly elastic collision then find the range of that second projectile. (Take g=10m/s2, assume the inclined plane is frictionless).
