50% Part (a) What is the acceleration in the horizontal direction for an object undergoing projectile motion? Zero. V Correct! *50% Part (b) How do you get the equations for projectile motion from the 2-dimensional kinematic equations? (Select all that apply) Set the velocity in the vertical direction to be zero. Set the acceleration in the vertical direction to be the gravitational acceleration. Set the initial position in the x-direction to be zero. Set the acceleration in the horizontal direction to be zero. OSet the initial position in the y-direction to be zero. Set the velocity in the horizontal direction to be zero.
