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

0m/s²

Explanation:

Given parameters:

Initial velocity of the boat = 8m/s

Final velocity  = 8m/s

Time taken  = 4s

Unknown:

Acceleration of the boat = ?

Solution:

Acceleration is the rate of change of velocity with time.

It is mathematically expressed as;

        A =

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 =   = 0m/s²

this means that the temperature of both substances will be equal
