- A large rock is dropped from the top of a high cliff. Assuming that air resistance can be ignored and that the acceleration has the constant value of 10 m/s^2. how fast would the rock be traveling 6 seconds after it is dropped? what is its speed in MPH?If a car is traveling with a constant velocity, what can you say about its acceleration?On a 200 km bike cycle ride, you ride the first 90 km at an average speed of 20 m/s. What mustyour average speed over the next 40 km be to have your average speed for the total 200 km be?(b) Given this average speed for the first 90 km, can you possibly attain an average speed of80 m/s for the total 200 km ride? Explain.
- 32. An object moves with constant acceleration 4.00 m/s² and over a time interval reaches a final velocity of 12.0 m/s. (a) If its original velocity is 6.00 m/s, what is its displacement during the time interval? (b) What is the distance it travels during this interval? (c) If its original velocity is -6.00 m/s, what is its dis- placement during this interval? (d) What is the total distance it travels during the interval in part (c)?Problem 5. An object is moving with an initial position of 28m from the origin with an initial velocity of -4m/s and constant acceleration of 8m/s². (1) How fast is the body moving after 2s? (2) What is its position 3s after the start? (3) When will it be 36m from the origin?A person is driving on Autobahn at a speed of 215 km/h and has to slam on his brakes to avoid collision.
