SELF-PACED PRACTICE PROBLEM 5.2 A 45.6lbs ball with an initial velocity of 2.36 m/s is rolling on rough surface slope and continues to accelerate at 89.6 m/s2, the slope has a kinetic friction of 285 N. How long it would take for the ball to stop? Okay now, a rolling ball problem. How original. rSELF-PACED PRACTICE PROBLEM 5.3 A 62.3kg astronaut throws a 2.20 lbs package with an acceleration of 0.98 m/s2. If the astronaut was pushed back with a distance of 3.25m, how much farther is the package from the starting position? How long has it been since the astronaut pushed the package? Now let's throw an astronaut for variety's sake.
