A car starts from rest and 5 seconds later it is going  .What is the car's average acceleration?

Quizplus · Accepted Answer

We can use the formula for average acceleration (a) = (v_f - v_i) / t, where v_f is the final velocity, v_i is the initial velocity, and t is the time interval. In this case, v_f = 11 m/s, v_i = 0 m/s, and t = 5 s. Plugging in the values, we get a = (11 m/s - 0 m/s) / 5 s = 2.2 m/s^2. Therefore, the answer is B.
