Question

Three projectile $A,B$ and $C$ are thrown from the same point in the same plane.Their trajectories are shown in the figure.Then which of the following statement is true :

• A. The time of flight is the same for all the three
• B. The launch speed is greatest for particle $C$
• C. The horizontal velocity component is greatest for particle $C$
• D. All of the above

Answer 1

Answer: (D)

All of the above

The time of flight only depends on vertical component of velocity and if A,B,C have same max height that means they have same vertical component of velocity i.e., same time of flight . (A) is correct.
If C covers maximum horizontal distance in same time as all three that means it has maximum horizontal velocity. (C) is correct.
If all of them have same vertical velocity and C have maximum horizontal velocity that implies C has highest total velocity. (B) is correct.
All the options are correct , (D) is correct . ( for single correct options only D)
