At which point on its path a projectile has the smallest speed?

An object of mass 5 kg is projecte with a velocity of 20ms^(-1) at an angle of 60^(@) to the horizontal. At the highest point of its path , the projectile explodes and breaks up into two fragments of masses 1kg and 4 kg. The fragments separate horizontally after the explosion, which releases internal energy such that K.E. of the system at the highest point is doubled. Calculate the separation betweent the two fragments when they reach the ground.

At highest point acceleration of projectile is zero.

At highest point velocity of projectile is …... ( theta = angle of projection).

A projectile is thorwn with a velocity of 50ms^(-1) at an angle of 53^(@) with the horizontal Detemrine the instants at which the projectile is at the same height

Assertion :- In projectile motion a particle is projected at some angle from horizontal. At highest point of its path radius of curvature is least. At highest point of path normal acceleration of projectile is equal to acceleration due to gravity.

A shell is fired from a cannon with a velocity v (m//sec.) at an angle theta with the horizontal direction. At the highest point in its path it explodes into two pieces of equal mass. One of the pieces retraces its path to the cannon and the speed (in m//sec. ) of the other piece immediately after the explosion is

At which position (point) pendulum of a clock have maximum speed ?

The trajectory of a projectile in a vertical plane is y=sqrt(3)x-2x^(2) . [g=10 m//s^(2)] Radius of curvature of the path of the projectile at the topmost point P is :-
