A tennis ball is hit with an initial velocity of 15 m/s at an angle of 40°. What is the horizontal distance of the ball after 2 seconds?
(round to the nearest meter)

Horizontal acceleration is 0 in a projectile motion

Explanation:

first we have to find the horizontal velocity

15cos40 = 11.49ms^-1

and then use the following equation to find the distance

the results is a decrease in air temperature with an increase of altitude.

explanation:

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
