Ashark swimming in the ocean sees a passing fish swimming by and accelerates at 2 m/s2 to a speed of 20 m/s to overtake it, doing so in 3 seconds. what was the shark’s initial speed? round to 1 decimal place and include unit in your response.

The answer to your question is:      is = 14 m/s

Step-by-step explanation:

Data

acceleration = 2 m/s² = a

final speed = 20 m/s = sf

time = 3 seconds = t

initial speed = ? = is

Formula

sf = is + at

is = sf - at

Substitution

                        is = 20 - (2)(3)

                        is = 20 - 6

                        is = 14 m/s
