... 31. A 200.0 kg astronaut and equipment move with a velocity of 2.00 m/s toward an orbiting spacecraft. How long will the astronaut need to fire a 100.0 N rocket backpack to stop the motion relative to the spacecraft? a. This is an impulse problem where we have to drain away the momentum of the astro ...

... When a ball enters a curve, even if its speed does not change, it is accelerating because its direction is changing. When a ball goes around a curve, the change in the direction of the velocity is toward the center of the curve. Acceleration toward the center of a curved or circular path is called c ...

PART 2 Answers to End-of-chapter Conceptual Questions
... 2. It is not possible to swing a mass in a horizontal circle above your head. Since gravity is always pulling down on the mass, an upward component of the tension force is required to balance gravity. As the speed of rotation increases, the angle relative to the horizontal may approach 0° but will n ...
