Explanation / Answer

A) durimg it is jetting

initial speed is Vi = 0 m/s

distance moved is S1 = 0.185 m

time is t = 0.168 s

using kinematic equation

S1 = (Vi*t)+(0.5*a*t^2)

0.185 = (0*t)+(0.5*a*0.168^2)

0.185 = 0.5*a*0.168^2

a = 13.1 m/s^2

B) time taken is t = 0.39-0.168 = 0.222 sec

distance covered is S = 0.429-0.185 = 0.244 m

Final speed is V = 0 m/s

then initial speed is Vo = (a*t) = 13.1*0.168 = 2.2 m/s

then

Using

S = (Vo*t)+(0.5*a*t^2)

0.244 = (2.2*0.222)+(0.5*a*0.222^2)

a = -9.92 m/s^2

magnitude is a = 9.92 m/s^2
