Question

Question 2 A car is traveling to the left at 20 m/s and it is accelerating to the left at a constant rate. After 5 seconds of time, the car is traveling to the right at 5 m/s. a. What is the acceleration of the car? b. How far does the car travel over the 5 seconds?

Question 3 A stone is thrown upward. When the stone is traveling downward with a speed that is twice that of the initial speed, it is located 10 meters below the initial launch height. Use 10 m/s/s downward as the acceleration from the Earth. a. What is the initial speed of the stone? b. What is the flight time of the stone from the initial to the final velocity?

Question 4 A stone is thrown downward. When the stone hits the ground 30 meters below, it is traveling at 40 m/s. Use 10 m/s/s downward as the acceleration from the Earth. a. What is the initial speed of the stone? b. What is the flight time of the stone from the initial to the final velocity?

Question 5 Here is a question where more than 1 set of two points (initial and final) are used to find the answer. A stone is dropped from the top of a building. The stone arrives at the top of the window at a speed of 5 m/s. The stone crosses a window in a time of 0.5 second. a. What is the height of the window? b. How fast is the stone traveling at the bottom of the window
