1. A baseball player is warming up and tosses a ball straight up into the air. The ball travels up until it reaches some maximum height, and then falls back down to the player's hand. If we neglect air resistance, then the magnitude of the acceleration of the ball is? A. largest the moment after it leaves the players hand. B. smallgst the moment after it leaves the player's...

The Empire State Building in New York City is 381 meters tall. If a penny were dropped from rest at that height, how many seconds would it take to strike the street below? Air resistance would make a significant difference in the real world case, but ignore air resistance for now. As a 5 kg ball rolls down a ramp, the net force on it is 15 N. What is its acceleration? A long-distance runner has an average speed of...

1. Teresa Drops a Stone. (Allotted Time - 40 minutes) Teresa drops a stone from rest from the top of an extremely tall building on a huge planet with essentially no atmosphere. You may assume that the stone experiences a constant gravitational acceleration as it falls to the planet’s surface, but the magnitude of this acceleration may not be equal to that on Earth. Let d1 be the distance the rock travels during the 1st second of its fall, let...

Lab 4: Introduction & Instructions Centripetal Acceleration Introduction Velocity is a vector with both a magnitude and a direction. Since acceleration is a measure of a change in velocity over time, it seems reasonable that either the magnitude of the velocity vector could be changing, or the direction, or both. If magnitude is changing only, then the motion occurs in one dimension and the principles of algebra can be applied to the equations of motion. But suppose the opposite case...
