Answer:
Acceleration, a = 6 m/s²
Explanation:
It is given that,
The police department is excited to have some new motorcycle units. one officer said that these motorcycles can go from 0 miles per hour to 80 miles per hour in just 6 seconds.
Initial speed of motorcycle, u = 0
Final speed, v = 80 miles/h = 35.8 m/s
Time taken, t = 6 s
The officer is describing the motorcycle's acceleration and it can be calculated by :
a = 5.966 m/s²
or a = 6 m/s²
Hence, the acceleration of the motorcycle is 6 m/s².

The question is incomplete, here is the complete question:
The rate of certain reaction is given by the following rate law:
At a certain concentration of
As we are given that:
Initial rate = 0.120 M/s
Expression for rate law for first observation:
....(1)
Expression for rate law for second observation:
....(2)
Dividing 2 by 1, we get:
Therefore, the initial rate of the reaction will be, 0.03 M/s
