A projectile is thrown at an angle of theta=45^(@) to the horizontal, reaches maximum reaches a maxium height of 16m , then

A projectile thrown at an angle of 30^@ with the horizontal has a range R_1 and attains a maximum height h_1 Another projectile thrown, with the same velocity, at an angle 30^@ with the vertical, has a range R_2 and attains a maximum height h_2 The relation between R_1 and R_2 is

A projectile thrown with an initial velocity of 10 ms^(-1) at an angle with the horizontal, has a range of 5 m. Taking g=10 ms^(-2) and neglecting air resistance, what will be the estimated value of alpha ?

A projectile thrown with an initial speed u and the angle of projection 15^@ to the horizontal has a range R . If the same projectile is thrown at an angle of 45^@ to the horizontal with speed 2 u , what will be its range ?
