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^@` .

A projectile is projected with a speed u at an angle theta with the horizontal. What is the speed when its direction of motion makes an angle theta//2 with the horizontal

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 projected with a speed u at an angle theta with the horizontal. What will be the speed of the particle when direction of motion of particle is at an angle alpha with the horizontal?

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 ?
