Question

the figure above shows the path of a ball tossed from a building. air resistance is ignored. at what point of the balls path shown in the figure above is the vertical component of the balls velocity zero? oa oc od ob question 9 which of the following is the motion of objects moving in two dimensions under the influence of gravity? directrix vertical velocity horizontal velocity projectile motion

Explanation:

Step1: Analyze projectile motion

In projectile - motion, at the highest point of the trajectory, the vertical component of velocity is zero. Point B is the highest point of the ball's path.

Step2: Recall motion under gravity

The motion of objects moving in two - dimensions under the influence of gravity is called projectile motion.

Answer:

Question 1: D. OB
Question 2: D. projectile motion
