"A farmer needs to get hay to cows in a frozen field. Using an airplane flying 40 m/s, at a height of 280 m, how far from the cow would she have to release the hay in order to hit the cow?" What is the horizontal velocity you would use to solve this problem?

x = 302 m

Explanation:

Given that,

Speed of an airplane, v = 40 m/s

Height, h = 280 m

40 m/s is the horizontal velocity we should use to solve the given problem.

Let t is the time when the hay will reach the ground. It can be calculated using second equation of motion as follows :

Here, u = 0 and a = g

Let the horizontal distance is x. It can be calculated as :

x = vt

x = 40 m/s × (7.55 s)

x = 302 m

Hence, at a distance of 302 m she have to release the hay in order to hit the cow.

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.
