A ball is thrown at an angle theta with the horizontal. Its time of flight is 2 s. Its horizontal range is 100 m. What is the horizontal component of velocity of projection ? Take g =10 ms^(-2) .

When a particle is projected at an angle to the horizontal, it has range R and time of flight t_(1) . If the same projectile is projected with same speed at another angle to have the saem range, time of flight is t_(2) . Show that: t_(1)t_(2)=(2R//g)

When a particle is projected at an angle to the horizontal, it has range R and time of flight t_(1) . If the same projectile is projected with same speed at another angle to have the saem range, time of flight is t_(2) . Show that: t_(1)t_(2)=(2R//g)

A body is projected at an angle theta with the horizontal. Derive an expression for its horizontal range. Show that there are two angles theta_(1) and theta_(2) projections for the same horizontal range, such that theta_(1)+theta_(2)=90^(@) .

What is a projectile ? Obtain an expression for: maximum height , time of flight and the horizontal range when a projectile is fired at an angle theta with the horizontal.
