The direction of velocity and acceleration of a projectile at the highest point on the trajectory are

The kinetic energy of a projectile at the highest point is-

The angle between the direction of velocity and acceleration at the highest point of a projectile path is______ .

A javelin thrown into air at an angle with the horizontal has a range of 200 m. If the time of flight is 5 second, then the horizontal component of velocity of the projectile at the highest point of the trajectory is

Acceleration of a particle under projectile motion at the highest point of its trajectory is :

The acceleration of a projectile relative to another projectile is

If theta is the angle between the velocity and acceleration of a projectile at a point of its path, its value when the projectile is at the highest point is :

Assertion At highest point of a projectile, dot product of velocity and acceleration is zero. Reason At highest point, velocity and acceleration are mutually perpendicular.

The question given below consist of an assertion and the reason . Use the following key to choose appropriate answer: Assertion : At the highest point velocity of the projectile is zero Reason : At the highest point of trajectory acceleration of the particle becomes zero for an instant .
