A particle is thrown with speed u of an angle theta with the horizontal when the particle makes an angle phi with the horizontal its speed changes to v

A particle is thrown with a speed u at an angle theta with the horizontal. When the particle makes an angle phi with the horizontal. Its speed changes to v :

A particle is thrown with the speed u at an angle alpha with the horizontal. When the particle makes an angle beta the horizontal , its speed will be

A stone is thrown with a velocity v at an angle theta with the horizontal.Its speed when it makes an angle beta with the horizontal is

A particle is thrown with a speed 60 ms^(-1) at an angle 60^(@) to the horizontal. When the particle makes an angle 30^(@) with the horizontal in downward direction, it's speed at that instant is v. What is the value of v^(2) in SI units ?

What is the radius of curvature of the parabola traced out by the projectile in which a particle is projected with a speed u at an angle theta with the horizontal, at a point where the velocity of particle makes an angle theta//2 with the horizontal.

A projectile is fired with a speed u at an angle theta with the horizontal. Find its speed when its direcrtion of motion makes an angle alpha with the horizontal.

Assertion A particle is projected with speed u at an angle theta with the horizontal. At any time during motion, speed of particle is v at angle alpha with the vertical, then v sin alpha is always constant throughout the motion. Reason In case of projectile motion, magnitude of radical acceleration at topmost point is maximum.

A particle is projected with speed 'u' at an angle 60^@ with horizontal, then find the speed when its angle with horizontal changes to 30^@ .

What is the radius of curvature of the parabola traced out by the projectile.Projected with a speed u=sqrt30 at angle theta=60^(@) with the horizontal at a point where the particle velocity makes an angle theta//2 with the horizontal ?
