Which of the following is true regarding the motion of the sphere in the vertical direction? assume the +y direction is up. (select all that apply.) at the moment the sphere leaves the ramp, the vertical component of the velocity of the sphere is zero. once the sphere leaves the ramp, the acceleration of the sphere in the vertical direction is 9.8 m/s2. once the sphere leaves the ramp, the acceleration of the sphere in the vertical direction is zero. at the moment the sphere leaves the ramp, the vertical component of the velocity of the sphere is same as its horizontal component. once the sphere leaves the ramp, the acceleration of the sphere in the vertical direction is −9.8 m/s2.
