For a 30 degree launch angle, the initial velocity(v0) is 3.12 m/s, the height at which the launcher is shot from has a height(h) of 1.17 m from the ground, travels at a time t =.673 s, and a horizontal displacement(change in X) of 1.82 m.

1(a). Calculate the speed(x and y component) of the projectile at a half way point through flight. (t=.673/2)

1(b). Calculate velocity of projectile at this point.

2. Calculate speed just before projectile hits ground.

3. Calculate angle the projectile makes with the horizontal just as projectile hits the ground.
