1. Write the kinematic equation:

v_f = v_i + a \cdot t

2. Rearrange to solve for

v_i

:

v_i = v_f - a \cdot t

3. Substitute the given values:

v_i = 8 - (0.3 \cdot 20)

4. Calculate the result:

v_i = 8 - 6 = 2 \, \text{m/s}

5. The original velocity is

v_i = 2 \, \text{m/s}

there are 500,000 bacteria at the end of a pin point. 1000 bacteria can make a person sick. then bacteria at the tip of a pin point can make 500 people sick. Also, many people do not know that bacteria can (reproduce). Let's say there are 5 bacteria and we leave it for 15 minutes. bacteria will multiply to 10. if left for up to 30 minutes, 20 bacteria will form. if left up to 45 minutes. bacteria will multiply up to 40. every 15 minutes the bacteria will double 2. if you start with five bacteria that reproduce every 15 minutes, how manu bacteria would you have after 12 hours ?
