Answer #1

a)Quantities that are constant are ay= -9.8m/s^2 through out the motion constant value and towards ground .

Vx is also constant as there is no ax so Vx is constant through out the motion .

ax is zero through out the motion . So ay,ax and Vx are constant .

b) ax is zero through out the motion as there is no horizontal component of acceleration
