You are encouraged to read each problem and practice the use of the strategy in the solution of the problem then click the button to check the answer or use the link to view the solution determine the acceleration of the car see answer answer a 810 m s s. What is the acceleration of the car first we identify the information that we are given in the problem vf 10 m sec vo 0 m sec time 20 seconds then we insert the given information into the acceleration formula a vf vo t a 10 m sec 0 m sec 20 sec solving the problem gives an acceleration value of 05 m sec2. Practice acceleration questions this is the currently selected item acceleration at a glance acceleration and is accelerating with a constant acceleration of 5 m s 2 2 2 the ambulance is attempting to pass a car which is moving at a constant velocity of 30m s get a hint for this problem however if you use a hint this problem . A proper answer must include a direction as well this is quite easy to do since the car is starting from rest and moving forward its acceleration must also be forward the ultimate complete answer to this problem is the car is accelerating at a 406 m s 2 forward we should convert the final speed to si units. Acceleration is a vector quantity that measures a change in speed or direction it is defined as a change in velocity per unit of time this quiz will cover acceleration problems you will need scratch paper a pencil and a calculator select the best answer from the choices a vf vi t a
