Question

Which statements describe projectile motion? Check all that apply.

Answer 1

In projectile motion we can say initial components of velocity is

$v_x = v_0 cos\theta$

$v_y = v_0 sin\theta$

now here horizontal motion is uniform motion as there is no force in this direction while in vertical direction due to gravity it will accelerate

so we have

$x = v_0 cos\theta * t$

$y = v_0 sin\theta * t - \frac{1}{2}gt^2$

so here we have x and y coordinates are related to each other as it will take same time to move the positions

so here correct options are

Projectile motion is a combination of horizontal and vertical motion.

The horizontal and vertical motions of a projectile are dependent on each other.

Answer 2

Answer:

C. Projectile motion is a combination of horizontal and vertical motion.

D. The horizontal and vertical motions of a projectile are independent.
