A child is sliding on a sled on snow at 1.50 m/s to the right. For the purposes of this problem, you may assume that the sled is frictionless on the snow. Part A Which of the following will result when you push on the sled/child in the opposite direction to the motion? Assume that the child is initially moving in the positive direction (to the right) and that the force is applied in the negative direction (to the left). Check all that apply. When you are pushing on the child to the left, you will feel a larger amount of force pushing you to the right. When the force is applied, the child will have an acceleration in the opposite direction of the motion. When you are pushing on the child to the left, you will feel an equal amount of force pushing you to the right. When the force is applied, the impulse on the child will be positive. When the force is applied, the child will immediately stop. When the force is applied, it will take a measurable amount of time for the child to slow to a stop. When the force is applied, the impulse on the child will be negative.
