    Harder 3U - projectile motion question

    From Patel 4U (Ex. 8B, Q5):



    I've got the first part but I'm stuck on the second part.

    I'm not sure what means - maybe it's a typo and meant .

    Yeah, I believe it’s a typo. Don’t think it refers to the instantaneous speed of the projectile, as that will unnecessarily complicate things.

    So does that solve the problem, or do you still want the solution ?

    I still haven't figured it out yet... hints or a solution would be helpful.

    Well here are some hints: consider the range of the projectile to be the radius of the circle, and take into account the change in Alpha. Also focus on the part that says on the circle and within and see when that happens.

    If you need further hints or a solution, let me know
