Help please :pensive:
A boat is initially sailing South at 8 meters per second. After 4 seconds, it is sailing North at 8 meters per second. What was the boat's acceleration?
Question 9 options:
0 ms2
32 ms
64 m
4 ms2

Answers

Answer: 0m/s²Explanation:Given parameters: Initial velocity of the boat = 8m/s Final velocity  = 8m/s Time taken  = 4sUnknown: Acceleration of the boat = ? Solution: Acceleration is the rate of change of velocity with time. It is mathematically expressed as;         A = [tex]\frac{v - u}{t}[/tex] A is the acceleration v is the final velocity u is the initial velocity t is the time taken     Insert the parameters and solve;   A = [tex]\frac{8-8}{4}[/tex]   = 0m/s²
