PhysicsHardsingle choice

A projectile is launched at $4 0^{\circ}$ to the horizontal. Its kinetic energy as a function of horizontal displacement $x$ :

Answer:

Solution:

At the top the projectile still has its horizontal speed, so $K E$ never reaches zero; the variation is smooth (quadratic in $x$ ). Option B.
