The main cause of error in this experiment is reaction time when the person starts and stops the stop clock. Error due to reaction time can be kept to a minimum by ...

Find the acceleration of a car, if it starts at 10 m/s and it reaches 30 m/s in 4 seconds. Final velocity v = 30 m/s. Initial velocity u = 10 m/s. The final velocity v – initial velocity u is 30 ...
