A projectile fired from the ground follows a parabolic path. The speed of the projectile is minimum at the top of its path.

The pathe of a projectile is

The path of a projectile is

During the motion of a projectile , the speed of the projectile is minimum at the top of its path. Is this statement true ? Give reason .

If upsilon_(e) is the escape velocity for earth when a projectile is fired from the surface of earth. Then, the escape velocity if the same projectile is fired from its centre is

If upsilon_(e) is the escape velocity for earth when a projectile is fired from the surface of earth. Then, the escape velocity if the same projectile is fired from its centre is

A projectile is fired from the origin with a velocity v_(0) at an angle theta with x-axis. The speed of the projectile at an altitude h is .
