Aprojectile is fired into the air, and it follows the parabolic path shown in the drawing, landing on the right. there is no air resistance. at any instant, the projectile has a velocity v overscript rightwards harpoon with barb upwards endscripts and an acceleration a overscript rightwards harpoon with barb upwards endscripts. which one or more of the drawings could not represent the directions for v overscript rightwards harpoon with barb upwards endscripts and a overscript rightwards harpoon with barb upwards endscripts at any point on the trajectory?

Answer : Neither option A nor option C could represent the directions for v overscript rightwards harpoon with barb upwards endscripts and a overscript rightwards harpoon with barb upwards endscripts at any point on the trajectory.

As the acceleration is always downward, and also in this question the only force acting is the projectiles weight. Therefore, it is experiencing downward acceleration at  any point of time.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
