Question

if a projectile is thrown at an upward angle instead of parallel to the ground, what will its trajectory look like? (1 point)
it will be a straight line upward at an angle, then another straight line back downward.
it will be the same as that of a projectile thrown parallel to the ground.
it will be in the shape of a hill.
it will constantly curve downward.

Explanation:

When a projectile is thrown at an upward angle, it has an initial vertical and horizontal velocity. Gravity acts as a constant - downward acceleration. The vertical velocity first decreases as it goes up, reaches zero at the maximum height, and then increases in the downward direction. The horizontal velocity remains constant (neglecting air - resistance). This results in a parabolic trajectory which looks like the shape of a hill.

Answer:

It will be in the shape of a hill.
