Average torque on a projectile of mass `m` (initial speed `u` and angle of projection `theta`) between initial and final positions `P` and `Q` as shown in figure, about the point of projection is :
.

A particle of mass m , initial speed u and angle of projection theta is projected as shown in the figure. Average torque on the projectile between initial and final positions P and Q about the point of projection is

The speed of a projectile at its maximum height is half of its initial speed. The angle of projection is

A particle of mass m is projected with a speed v_(0) at an angle of projection theta with horizontal. Find the torque of the weight of the particle about the point of projection after time (v_(0)sintheta)/(g)

The speed of a projectile at its maximum height is half of its initial speed. The angle of projection is .
