a. The vertical component of its velocity is constant
b. The horizontal component of its velocity is increasing
c. The vertical component of its acceleration is increasing
d. The horizontal component of its acceleration is increasing
e. The horizontal component of its velocity is constant

Answer 1

The horizontal component of its velocity is constant

Answer 2

sure?

Answer 3

Close to earth , gravity down , toward the earth

Answer 4

...therefore there is no force in the horizontal direction
=> no acceleration in the horizontal direction
=> constant horizontal velocity

Answer 5

thanks
