An experimental rocket car starting from rest reaches a speed of 600 km/h after a straight 370 m run on a level salt flat. Assuming that acceleration is constant, answer the following questions.
a)What was the time of the run? (in seconds)
b)What is the magnitude of acceleration? (in m/s^2)

    first convert 600km/h to m/s then use the equation
    final velocity suqared = initial velocity squared plus 2 times aceleration times distance. remember initial is 0m/s. Then once you find acceleration use the equation final velocity equals initial velocity plus acceleration times time to solve for the time.
