When a projectile is at the highest point of its trajectory, the directions of its velocity and acceleration are


Correct option is

Perpendicular to each other

At the highest point of the trajectory, the velocity of the projectile is parallel to the ground but its acceleration is directed vertically downwards.



The maximum height attained by a projectile and its horizontal range are equal to each other if the projectile is projected at an angle θ given by


ball is projected horizontal with a velocity of 5 ms-1 from the top of a building 19.6 m high. How long will the ball take to hit the ground?


bomb is dropped from an aero plane when it is at a height h directly above a target. If the aero plane is moving horizontally at a speed v, the distance by which the bomb will miss the target is given by


missile is fired for maximum range at your town from a place in the enemy country 100 km away from your town. If the missile is first detected at its half – way point, how much warning time will you have? Take g = 10 ms-2.
