Q.

A bullet is dropped from the same height when another bullet is fired horizontally. They will hit the ground

Q. Two bullets are fired horizontally, simultaneously and with different velocities from same place. Which bullet will hit the ground earlier?

Q. Two bullets are fired horizontally with different velocities from the same height. Which one will reach the ground first?

Q. In the given figure point A and C are on the horizontal ground & A and B are in same vertical plane. Simultaneously bullets are fired from A, B and C and they collide at D. The bullet at B is fired horizontally with speed of $\frac{72}{5}$ km/hr and the bullet at C is projected vertically upward at velocity of $\frac{54}{5}$ km/hr. Find velocity of the bullet projected from A in m/s.
