The acceleration rounded off to the nearest 100th is: -2.14 m/s^2
Step-by-step explanation:
Acceleration can be defined as the change in velocity over time.
The acceleration is negative in case of slowing down as the velocity goes from a higher value to lower value.
The formula for acceleration is:
[tex]a=\frac{Change\ in\ velocity}{time}\\a=\frac{v_f-v_i}{t}\\Here,\\v_f\ is\ final\ velocity\\v_1\ is\ initial\ velocity\\t\ is\ time[/tex]
Given
v_f = 230 m\s
v_i = 245 m\s
t = 7
Putting the values
[tex]a=\frac{230-245}{7}\\=\frac{-15}{7}\\=-2.14\ ms^{-2}[/tex]
Hence,
The acceleration rounded off to the nearest 100th is: -2.14 m/s^2
