Question

What points in its trajectory does a projectile have its minimum and maximum speed?

Answer 1

Answer:

Maximum velocity

At projection point ( let origin )

And last point ( R , 0 )

Minimum Velocity

At maximum height

Coordinates :- ( R/2 , h )

Where

$r = \frac{u \sin(2 \alpha ) }{g} \: and \: \: \: h = \frac{ {u}^{2} \sin {}^{2} ( \alpha ) }{2g}$
