Asked by college
The question has three parts, it looks like a lot but it is just description, trying to understand relationships.
1. You toss a coin straight up into the air. Sketch on the axes below the velocity-time acceleration-time graphs of the coin from the instant it leaves your hand until the instant it returns to your hand. Assume that the positive direction y is upward. Indicate with arrows on your graphs the moment when the coin reaches its highest point.
2. Based on your knowledge of the gravitational force near the surface of the Earth, and on Newton’s second law, explain the sign and magnitude of the acceleration of the coin in question 1 during the three portions of its motion: on the way up, at the instant when it reaches its highest point, and on the way down.
3. Based on the way the velocity is changing, explain the sign and magnitude of the acceleration of the coin in question 1 during the three portions of its motion: on the way up, at the instant when it reaches its highest point, and on the way down.
