At what angle should a body he projected with a velocity `24 ms^(-1)` just to pass over the obstacle `14 m` high at a distance of `24 m` [Take `g = 10ms^(-2)`]

At what angle should a body be projected with a velocity 20 ms^(-1) just to pass over the obstacle 12 m high at a horizontal distance of 24 m ? Take g= 10^-2) .

At what angle should a body be projected with a velocity 24 ms^(-1) . Just to pass over the obstacle 16 m high at a horizontal distance of 32 m ? Take g = 10 ms^(-2) .

At what angle of elevation , should a projectile be projected with velocity with velocity 20 ms^(-1) , so as to reach a maximum height of 10 m ?

At what angle of elevation , should a projectile be projected with velocity with velocity 20 ms^(-1) , so as to reach a maximum height of 10 m ?

A body is projected with a velocity 60 ms^(-1) vertically upwards the distance travelled in last second of its motion is [g=10 ms^(-1)]
