What is the path followed by a projectile under the influence of gravity alone?

What is the shape of the trajectory of a projectile?

At what point in the path of a projectile is the speed minimum?

At t = 0 on the planet Gravitus Increasicus, a projectile is fired withspeed v0 at an angle θ above the horizontal. This planet is a strangeone, in that the acceleration due to gravity increases linearly with time,starting with a value of zero when the projectile is fired. In other words,g(t) = βt, where β is a given constant. What horizontal distance doesthe projectile travel? What should θ be to maximize this distance?
