Question

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.)

2) Once the sphere leaves the ramp, the acceleration of the sphere in the vertical direction is 9.8 m/s2

3) Once the sphere leaves the ramp, the acceleration of the sphere in the vertical direction is zero.

4) At the moment the sphere leaves the ramp, the vertical component of the velocity of the sphere is zero

5) Once the sphere leaves the ramp, the acceleration of the sphere in the vertical direction is ?9.8 m/s2.

I know it will have an acceleration of 9.8 m/s^2, so I put 5) if down is negative, but got it wrong. I also put 1) and 5) and that wrong as well.

It's 4 & 5
