The maximum range of a projectile fired with some initial velocity is found to be 1000 metre in the absence of wind and air resistance. The maximum height (H) reached by this projectile is The maximum range of a projectile fired with some initial velocity is found to be 1000 metre in the absence of [...]

A projectile is thrown with initial velocity v0 and angle 30 degree with the horizontal. If it remains in the air for 1 s, what was its initial velocity ? A projectile is thrown with initial velocity v0 and angle 30 degree with the horizontal. If it remains in the air for 1 s what [...]
