Question $1(1$ point$)$: What is different between "Displacement" and "Distance"?Question $2(1$ point$)$: A projectile is fired at an angle of $30\backslash$deg from the horizontal with some initial speed. Firing the projectile at what other angle results in the same horizontal range if the initial speed is the same in both cases? Neglect air resistance.Question $3(1$ point$)$: Describe the path of a moving body in the event that its acceleration is constant in magnitude at all times and $($a$)$ perpendicular to the velocity; $($b$)$ parallel to the velocity.
