Answer:
-4m/s²
Step-by-step explanation:
<u>Given</u><u> </u><u>Equation</u><u> of</u><u> </u><u>velocity</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Differenciation</u><u> </u><u>of </u><u>first </u><u>order</u><u> </u><u>will </u><u>give </u><u>acclⁿ</u><u> </u><u>:</u><u>-</u><u> </u>
- v = 6t² - 4t -2
- dv/dt = d(6t² - 4t -2)/dt
- dv/dt = 2*6 t¹ - 4*1 t⁰ - 0
- dv/dt = 12t - 4
- a = 12t - 4
<u>At </u><u>t </u><u>=</u><u> </u><u>0</u><u> </u><u>,</u>
- a = 12*0 - 4 m/s²
- a = -4m/s²
