You first push him from behind with a force of magnitude Fi directed downward at an angle of 25o below the horizontal. After a while you decide to pull him with a force of magnitude F2 directed upward at the same angle above the hoirzontal. In both cases the sled moves with the same acceleration and friction is negligible. Which of the following statements is true regarding the two forces you used? O not enough information Additional Materials Reading

Explanation / Answer
