Question

An object is launched at a known speed and a known angle with respect to the horizintal. Check all questions that simply state that the horizontal component of the velocity vector does not change. (Ignore air resistance.)x = xo + vox t + 1/2 ax t2 vx = vox + ax t vx2 = vox2 + 2 ax (x-xo) y = yo + voy t + 1/2 ay t2 vy = voy + ay t vy2 = voy2 + 2 ay (y-y A bullet is fired horizontally at the same time that a steel ball bearing is dropped from the same height. (Ignore air resistance.) Because the ball bearing travels the shorter distance, it hits the ground first. Both hit the ground at the same time. Because the bullet has the faster starting velocity, it hits the ground first.
