Which of the following is true regarding motion of the sphere in the horizontal

Question

Which of the following is true regarding motion of the sphere in the horizontal direction during this part of its motion? Assume the +x direction is to the left. Neglect friction or air drag. (Select all that apply.)
1. The acceleration of the sphere in the horizontal direction is 9.8 m/s2

2. The horizontal component of the velocity is constant.

3. The acceleration of the sphere in the horizontal direction is zero.

4. The horizontal component of the velocity depends on its distance from the edge of the ramp.

5. The horizontal component of the velocity increases as the sphere moves away from the ramp.

6. The horizontal component of the velocity decreases as the sphere moves away from the ramp.

7. The acceleration of the sphere in the horizontal direction is ?9.8 m/s2

8. The horizontal component of the velocity is zero.

Explanation / Answer

1) False (since there is no force, a = 0)

2) True (since, a = 0)

3) true

4) False (it depends h1)

5) False

6) False (since vx is constant)

7) False (since a = 0)

8) False (it has non zero velcoity)
