Sample Problems. 1. What is the acceleration of a vehicle that changes its velocity from 100km/h to a dead stop in 10 s? 2. What is the instantaneous velocity of a freely falling object 10 s after it is released from a position of rest? What is its average velocity during this 10-s interval? How far will it fall during this time? 3. A car takes 10 s to go from v = 0m / s to v = 25m / s at approximately constant acceleration. If you wish to find the distance traveled using the equation d = 1 2 at 2 , what value should you use for a ? 4. A reconnaissance plane flies 600 km away from its base at 200 km/h, then flies back to its base at 300 km/h. What is its average speed? 5. A car travels along a certain road at an average speed of 40 km/h and returns along the same road at an average speed of 60 km/h. Calculate the average speed for the round trip. ( Don’t say 50 km/h! ) 6. What is the acceleration of a 40-kg block of cement when pulled side- ways with a net force of 200 N? 7. What is the acceleration of a 20-kg pail of cement that is pulled upward
