Answer:
Displacement = 72m
Acceleration = 4 [tex]m/s^{2}[/tex]
Explanation:
The jet ski increases its speed from zero to 24 m/s in 6 seconds.
We are supposed to find the displacement and its acceleration rate.
Displacement is the distance it covers in this time interval.
Acceleration is the rate of increase of speed.
Acceleration = [tex]\frac{change in velocity}{time}[/tex]
Acceleration = [tex]\frac{24 - 0}{6}[/tex]
Acceleration = 4 [tex]m/s^{2}[/tex]
According to equation of motion ,
[tex]v^{2}-u^{2} = 2\times a\times s[/tex]
[tex]24^{2} - 0 = 2\times 4\times s[/tex]
s = [tex]\frac{576}{8}[/tex]
Displacement , s = 72 m
