1. Adam grabs Sarah by the hand and tries to pull her. She tries to remain standing without moving. A student analyzes the situation as follows. "If Adam's force on Sarah is greater than her force on him, he can get her to move. Otherwise, she'll be able to stay where she is. "What's wrong with this analysis? 2.You hit a tennis ball against a wall. Explain any and all incorrect ideas in the following description of the physics involved: "According to Newton's third law, there has to be a force opposite to your force on the ball. The opposite force is the ball's mass, which resists acceleration, and also air resistance."

Can anyone help me to answer these two questions I really need it right away for today ASAP.
