• Q1
What variables are given and implied in the situation above?
v(x)=20m/s, d(x)=60m, a(y)=-9.8m/s^2, v(iy)=0m/s
Pick the other answer. The horizontal velocity and horizontal displacement are both given. The vertical acceleration is from gravity. Because the projectile was launched horizontally, the initial vertical velocity is 0m/s.
