![a. If the Pressure produced by the gas cylinder of the motor of the
rocket is governed by the below equation:
P = sin (V)cos (V)
And the energy is given by:
v2
W =| PdV
Jvi
If V2=2V1, Find W.
What will be W if V2=4V1.

iii. Use Matlab or excel to plot the Energy in the interval [0,21]
b. If the vibration at the boundaries of the piston of the motor is
given by:
v(t) = at + b; a, b are constants, you may choose any integer
value not equal to zero for any of them.
v(t) = te(-t).
i. v(t) = 5sin(2at) cos(4wt)
find the average and rms vibration for each case:
