(b) How far has the ball travelled in that interval of 12 s? (c) Solve for the displacement of the ball in every second interval. Show the complete 12 solutions of the displacement. 2. What is the average acceleration in m/s? of a moving object with an initial velocity of 12.5m/s and having a final velocity of 25 m/s in a period of 5 minutes? 3. The average acceleration of a moving object is 12 m/s?. If the Object moves from with an initial velocity of 2.5 m/s in a period of 12 minutes, what is its final velocity? 4. The average acceleration of a moving object is 17.5 m/s?. If the Object reaches its final velocity of 75 m/s in a period of 15 minutes, what is its initial velocity? 5. The average acceleration of a moving object is 25m/s?. If the object starts in 10.0 m/s initial velocity and reaches its final velocity of 15 mis consuming a final time of 75 second, what is its initial time? 6. The average acceleration of a moving object is 1.25 m/s?. If the object starts in 2.5 m initial velocity and reaches its final velocity of 22.5 m/s in an initial time of 30 seconds, what is its final time? 7. What is the average velocity in m/s of a moving object that starts with 10km marks to 15 km in a period of 5 minutes? 8. If a ball rolls down an inclined plane with uniform acceleration of 1.5 m/s? with an instant velocity of 0.75 m/s. What is the velocity of the ball 20 s later? How far has the ball traveled in that interval of 20 s? How far did the ball travel during the twelfth seconds? 9. How high is a building if it takes 5 seconds for a ball to hit the floor Pretend the object was dropped from the rooftop and a man was holding the ball at a height of 1 meter before letting it go. 10.
