-30 m

Which of the following scenarios would result in a projectile reaching a greater vertical height?

Launching it with a higher initial velocity at a smaller angle to the horizontal

What would happen to the range of a projectile if both its initial velocity and launch angle are doubled?

The range would be doubled.

Solve a physics problem involving projectile motion, where an object of mass 2000 g covers a maximum vertical distance of 6 m when projected at an angle of 45°. Calculate the initial velocity of the object using the given parameters and equations.
